+## Making changes
+
+### Tests
+
+Whenever possible, changes should be accompanied by non-trivial tests that meaningfully exercise the core functionality of the new code being introduced.
+
+All tests are in the `Test/` directory at the repo root. Fast unit tests are in the `Test/L0` directory and by convention have the suffix `L0.cs`. For example: unit tests for a hypothetical `src/Runner.Worker/Foo.cs` would go in `src/Test/L0/Worker/FooL0.cs`.
+
+Run tests using this command:
+
+```sh
+cd src && ./dev.sh test
+```
+
+### Formatting
+
+After editing .cs files, always format the code using this command:
+
+```sh
+cd src && ./dev.sh format
+```
+
+### Feature Flags
+
+Wherever possible, all changes should be safeguarded by a feature flag; `Features` are declared in [Constants.cs](src/Runner.Common/Constants.cs).

+**Status**: Accepted
+
+## Context
+
+We released [composite run steps](https://github.com/actions/runner/pull/554) last year which started our journey of reusing steps across different workflow files. To continue that journey, we want to expand composite run steps into composite actions.
+
+We want to support the `uses` steps from workflows in composite actions, including:
+  - Container actions
+  - Javascript actions
+  - Other Composite actions (up to a limit of course!)
+  - The pre and post steps these actions can generate
+
+## Guiding Principles
+
+- Composite Actions should function as a single step or action, no matter how many steps it is composed of or how many levels of recursion it has
+  - In the future we may add a configurable option to make this no longer the case
+- A workflow author should not need to understand the inner workings of a composite action in order to use it
+- Composite actions should leverage inputs to get values they need, they will not have full access to the `context` objects. The secrets context will **not** be available to composite actions, users will need to pass these values in as an input.
+- Other Actions should **just work** inside a composite action, without any code changes
+
+## Decisions
+
+### Composite Recursion Limit
+
+- We will start with supporting a recursion limit of `10` composite actions deep
+- We are free to bump this limit in the future, the code will be written to just require updating a variable. If the graph evaluates beyond the recursion limit, the job will fail in the pre-job phase (The `Set up job` step).
+- A composite actions interface is its inputs and outputs, nothing else is carried over when invoking recursively.
+
+### Pre/Post Steps in nested Actions
+
+- We do not plan on adding the ability to configure a customizable pre or post step for composite actions at this time. However, we will execute the pre and post steps of any actions referenced in a composite action.
+- Composite actions will generate a single pre-step and post-step for the entire composite action, even if there are multiple pre-steps and post-steps in the referenced actions.
+  - These steps will execute following the same ordering rules we have today, first to run has their pre step run first and their post step run last.
+  - For example, if you had a composite action with two pre steps and two posts steps:
+
+  ```
+  - uses: action1
+  - uses: composite1
+  - uses: action2
+  ```
+
+  The order of execution would be:
+
+  ```
+  - prestep-action1
+  - prestep-composite1
+    - prestep-composite1-first-action-referenced
+    - prestep-composite1-second-action-referenced
+  - prestep-action2
+  - the job steps
+  - poststep-action2
+  - poststep-composite1
+    - poststep-composite1-the-second-action-referenced
+    - poststep-composite1-first-action-referenced
+  - poststep-action1
+  ```
+
+#### Set-state
+
+- While the composite action has an individual combined pre/post action, the `set-state` command will not be shared.
+- If the `set-state` command is used during a composite step, only the action that originally called `set-state` will have access to the env variable during the post run step.
+  - This prevents multiple actions that set the same state from interfering with the execution of another action's post step.
+
+### Resolve Action Endpoint changes
+
+- The resolve actions endpoint will now validate policy to ensure that the given workflow run has access to download that action.
+  - Older GHES/GHAE customers with newer runners will be locked out of composite uses steps until they upgrade their instance.
+
+### Local actions
+- Local actions will expand the tree, perform policy checks, and download actions Just in Time when the step is running.
+- Like current local actions, we will not support presteps. If an action is running local, by the time we know that, the time to run presteps have already passed.
+
+### If, continue-on-error, timeout-minutes - Not being considered at this time
+
+- `if`, `continue-on-error`, `timeout-minutes` could be supported in composite run/uses steps. These values were not originally supported in our composite run steps implementation.
+  - Browsing the community forums and runner repo, there hasn't been a lot of noise asking for these features, so we will hold off on them.
+- These values passed as input into the composite action will **not** be carried over as input into the individual steps the composite action runs.
+
+### Defaults - Not being considered at this time
+
+- In actions, we have the idea of [defaults](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#defaultsrun) , which allow you to specify a shell and working directory in one location, rather then on each step.
+- However, `shell` is currently required in composite run steps
+  - In regular run steps, it is optional, and defaults to a different value based on the OS.
+- We want to prioritize the right experience for the consumer, and make the action author continue to explicitly set these values. We can consider improving this experience in the future.
+
+## Consequences
+
+- Workflows are now more reusable across multiple workflow files
+- Composite actions implement most of the existing workflow run steps, with room to expand these in the future
+- Feature flags will control this rollout

+# ADR 1438: Support Conditionals In Composite Actions
+
+**Date**: 2021-10-13
+
+**Status**: Accepted
+
+## Context
+
+We recently shipped composite actions, which allows you to reuse individual steps inside an action. 
+However, one of the [most requested features](https://github.com/actions/runner/issues/834) has been a way to support the `if` keyword.
+
+### Goals
+- We want to keep consistent with current behavior
+- We want to support conditionals via the `if` keyword
+- Our built in functions like `success` should be implementable without calling them, for example you can do `job.status == success` rather then `success()` currently.
+
+### How does composite currently work?
+
+Currently, we have limited conditional support in composite actions for `pre` and `post` steps. 
+These are based on the `job status`, and support keywords like `always()`, `failed()`, `success()` and `cancelled()`. 
+However, generic or main steps do **not** support conditionals.
+
+By default, in a regular workflow, a step runs on the `success()` condition. Which looks at the **job** **status**, sees if it is successful and runs.
+
+By default, in a composite action, main steps run until a single step fails in that composite action, then the composite action is halted early. It does **not** care about the job status.
+Pre, and post steps in composite actions use the job status to determine if they should run.
+
+### How do we go forward?
+
+Well, if we think about what composite actions are currently doing when invoking main steps, they are checking if the current composite action is successful. 
+Lets formalize that concept into a "real" idea.
+
+- We will add an `action_status` field to the github context to mimic the [job's context status](https://docs.github.com/en/actions/learn-github-actions/contexts#job-context).
+  - We have an existing concept that does this `action_path` which is only set for composite actions on the github context.
+- In a composite action during a main step, the `success()` function will check if `action_status == success`, rather then `job_status == success`. Failure will work the same way. 
+  - Pre and post steps in composite actions will not change, they will continue to check the job status.
+
+
+### Nested Scenario
+For nested composite actions, we will follow the existing behavior, you only care about your current composite action, not any parents. 
+For example, lets imagine a scenario with a simple nested composite action
+
+```
+- Job
+  - Regular Step
+  - Composite Action
+    - runs: exit 1
+    - if: always()
+      uses: A child composite action
+        - if: success()
+          runs: echo "this should print"
+        - runs: echo "this should also print"
+    - if: success()
+      runs: echo "this will not print as the current composite action has failed already"
+      
+```
+The child composite actions steps should run in this example, the child composite action has not yet failed, so it should run all steps until a step fails. This is consistent with how a composite action currently works in production if the main job fails but a composite action is invoked with `if:always()` or `if: failure()`
+
+### Other options explored
+We could add the `current_step_status` to the job context rather then `__status` to the steps context, however this comes with two major downsides:
+- We need to support the field for every type of step, because its non trivial to remove a field from the job context once it has been added (its readonly)
+  - For all actions besides composite it would only every be `success`
+  - Its weird to have a `current_step` value on the job context
+- We also explored a `__status` on the steps context.
+  - The `__` is required to prevent us from colliding with a step with id: status
+  - This felt wrong because the naming was not smooth, and did not fit into current conventions.
+
+### Consequences
+- github context has a new field for the status of the current composite action.
+- We support conditional's in composite actions
+- We keep the existing behavior for all users, but allow them to expand that functionality.

+# ADR: Notification Hooks for Runners
+
+## Context
+
+This ADR details the design changes for supporting custom configurable hooks for on various runner events. This has been a long requested user feature [here](https://github.com/actions/runner/issues/1543), [here](https://github.com/actions/runner/issues/699) and [here](https://github.com/actions/runner/issues/1116) for users to have more information on runner observability, and for the ability to run cleanup and teardown jobs. 
+
+This feature is mainly intended for self hosted runner administrators.
+
+**What we hope to solve with this feature**
+1. A runner admininstrator is able to add custom scripts to cleanup their runner environment at the start or end of a job
+2. A runner admininstrator is able to add custom scripts to help setup their runner environment at the beginning of a job, for reasons like [caching](https://github.com/actions/runner/issues/1543#issuecomment-1050346279)
+3. A runner administrator is able to grab custom telemetry of jobs running on their self hosted runner
+
+**What we don't think this will solve**
+- Policy features that require certain steps run at the beginning or end of all jobs
+  - This would be better solved to in a central place in settings, rather then decentralized on each runner. 
+  - The Proposed `Notification Hooks for Runners` is limited to self hosted runners, we don't beileve Policy features should be
+- Reuse scenarios between jobs are covered by [composite actions](https://docs.github.com/en/actions/creating-actions/creating-a-composite-action) and [resuable workflows](https://docs.github.com/en/actions/using-workflows/reusing-workflows)
+- Security applications, security should be handled on the policy side on the server, not decentralized on each runner
+
+## Hooks
+- We will expose 2 variables that users can set to enable hooks  
+  - `ACTIONS_RUNNER_HOOK_JOB_STARTED`
+  - `ACTIONS_RUNNER_HOOK_JOB_COMPLETED`
+
+You can set these variables to the **absolute** path of a `.sh` or `.ps1` file.
+
+We will execute `pwsh` (fallback to `powershell`) or `bash` (fallback to `sh`) as appropriate.
+- `.sh` files will execute with the args `-e {pathtofile}`
+- `.ps1` files will execute with the args `-command \". '{pathtofile}'\"`
+
+We will **not** set the [standard flags we typically set](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idstepsshell) for `runs` commands. So, if you want to set `pipefail` on `bash` for example, you will need to do that in your script.
+
+### UI
+We want to ensure the experience for users invoking workflows is good, if hooks take too long, you may feel your job is delayed or broken. So, much like `Set Up Job`, we will generate two new steps automatically in your job, one for each configured hook: 
+- `Set up runner`  
+- `Complete runner` 
+
+These steps will contain all of the output from invoking your hook, so you will have visibility into the runtime. We will also provide information on the path to the hook, and what shell we are invoking it as, much like we do for `run: ` steps.
+
+### Contexts
+When running your hooks, some context on your job may be helpful.
+- The scripts will have access to the standard [default environment variables](https://docs.github.com/en/actions/learn-github-actions/environment-variables#default-environment-variables)
+  - Some of these variables are step specific like `GITHUB_ACTION`, in which case they will not be set
+- You can pull the full webhook event payload from `GITHUB_EVENT_PATH`
+
+### Commands
+Should we expose [Commands](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions) and [Environment Files](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#environment-files)

However, there are some limitations:
+- [save-state](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#sending-values-to-the-pre-and-post-actions) will **not** be supported, these are not traditional steps with pre and post actions
+- [set-output](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#using-workflow-commands-to-access-toolkit-functions) will **not** be supported, there is no `id` as this is not a traditional step
+
+
+### Environment Files
+We will also enable [Environment Files](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions#environment-files) to support setup scenarios for the runner environment.
+
+While a self hosted runner admin can [set env variables](https://docs.github.com/en/actions/hosting-your-own-runners/using-a-proxy-server-with-self-hosted-runners#using-a-env-file-to-set-the-proxy-configuration), these apply to all jobs. By enabling the ability to `add a path` and `set an env` we give runner admins the ability to do this dynamically based on the [workflows environment variables](https://docs.github.com/en/actions/learn-github-actions/environment-variables#default-environment-variables) to empower setup scenarios.
+
+
+### Exit codes
+These are **synchronous** hooks, so they will block job execution while they are being run. Exit code 0 will indicate a successful run of the hook and we will proceed with the job, any other exit code will fail the job with an appropriate annotation.
+- There will be no support for `continue-on-error`
+
+## Key Decisions
+- We will expose 2 variables that users can set to enable hooks  
+  - `ACTIONS_RUNNER_HOOK_JOB_STARTED`
+  - `ACTIONS_RUNNER_HOOK_JOB_COMPLETED`
+- Users can set these variables to the path of a `.sh` or `.ps1` file, which we will execute when Jobs are started or completed.
+  - Output from these will be added to a new step at the start/end of a job named `Set up runner` or `Complete runner`. 
+    - These steps will only be generated on runs with these hooks
+- These hooks `always()` execute if the env variable is set
+- These files will execute as the Runner user, outside of any container specification on the job
+- These are **synchronous** hooks
+  - Runner admins can execute a background process for async hooks if they want
+  - We will fail the job and halt execution on any exit code that is not 0. The Runner admin is responsible for returning the correct exit code and ensuring resilency. 
+    - This includes that the runner user needs access to the file in the env and the file must exist
+    - There will be no `continue-on-error` type option on launch
+    - There will be no `timeout` option on launch
+
+## Consequences
+- Runner admins have the ability to tie into the runner job execution to publish their own telemetry or perform their own cleanup or setup
+- New steps will be added to the UI showcasing the output of these hooks

+# ADR 0000: Container Hooks
+
+**Date**: 2022-05-12
+
+**Status**: Accepted
+
+# Background
+
+[Job Hooks](https://github.com/actions/runner/blob/main/docs/adrs/1751-runner-job-hooks.md) have given users the ability to customize how their self hosted runners run a job.
+Users also want the ability to customize how they run containers during the scope of the job, rather then being locked into the docker implementation we have in the runner. They may want to use podman, kubernetes, or even change the docker commands we run. 
+We should give them that option, and publish examples how how they can create their own hooks.
+
+# Guiding Principles
+- **Extensibility** is the focus, we need to make sure we are flexible enough to cover current and future scenarios, even at the cost of making it harder to utilize these hooks
+- Args should map **directly** to yaml values provided by the user. 
+  - For example, the current runner overrides `HOME`, we can do that in the hook, but we shouldn't pass that hook as an ENV with the other env's the user has set, as that is not user input, it is how the runner invokes containers
+
+## Interface
+- You will set the variable `ACTIONS_RUNNER_CONTAINER_HOOKS=/Users/foo/runner/hooks.js` which is the entrypoint to your hook handler.
+  - There is no partial opt in, you must handle every hook 
+- We will pass a command and some args via `stdin`
+- An exit code of 0 is a success, every other exit code is a failure
+- We will support the same runner commands we support in [Job Hooks](https://github.com/actions/runner/blob/main/docs/adrs/1751-runner-job-hooks.md)
+- On timeout, we will send a sigint to your process. If you fail to terminate within a reasonable amount of time, we will send a sigkill, and eventually kill the process tree.
+
+An example input looks like
+```json
+{
+  "command": "job_cleanup",
+  "responseFile": "/users/thboop/runner/_work/{guid}.json",
+  "args": {},
+  "state": 
+  {
+      "id": "82e8219701fe096a35941d869cf8d71af1d943b5d3bdd718850fb87ac3042480"
+  }
+}
+```
+
+`command` is the command we expect you to invoke
+`responseFile` is the file you need to write your output to, if the command has output
+`args` are the specific arguments the command needs
+`state` is a json blog you can pass around to maintain your state, this is covered in more details below.
+
+### Writing responses to a file
+All text written to stdout or stderr should appear in the job or step logs. With that in mind, we support a few ways to actually return data:
+1. Wrapping the json in some unique tag and processing it like we do commands
+2. Writing to a file
+
+For 1, users typically view logging information as a safe action, so we worry someone accidentialy logging unsantized information and causing unexpected or un-secure behavior. We eventually plan to move off of stdout/stderr style commands in favor of a runner cli. 
+Investing in this area doesn't make a lot of sense at this time.
+
+While writing to a file to communicate isn't the most ideal pattern, its an existing pattern in the runner and serves us well, so lets reuse it.
+
+### Output
+Your output must be correctly formatted json. An example output looks like:
+
+```
+{
+  "state": {},
+  "context"
+  {
+    "container" : 
+    {
+      "id": "82e8219701fe096a35941d869cf8d71af1d943b5d3bdd718850fb87ac3042480"
+      "network": "github_network_53269bd575974817b43f4733536b200c"
+    }
+    "services": {
+      "redis": {
+        "id": "60972d9aa486605e66b0dad4abb638dc3d9116f566579e418166eedb8abb9105",
+        "ports": {
+          "8080": "8080"
+        },
+      "network": "github_network_53269bd575974817b43f4733536b200c"
+    }
+  }
+  "alpine: true,
+}
+```
+
+`state` is a unique field any command can return. If it is not empty, we will store the state for you and pass it into all future commands. You can overwrite it by having the next hook invoked return a unique state.
+
+Other fields are dependent upon the command being run.
+
+### Versioning
+We will not version these hooks at launch. If needed, we can always major version split these hooks in the future. We will ship in Beta to allow for breaking changes for a few months.
+
+### The Job Context
+The [job context](https://docs.github.com/en/actions/learn-github-actions/contexts#example-contents-of-the-job-context) currently has a variety of fields that correspond to containers. We should consider allowing hooks to populate new fields in the job context. That is out of scope for this original release however.
+
+## Hooks
+Hooks are to be implemented at a very high level, and map to actions the runner does, rather then specific docker actions like `docker build` or `docker create`. By mapping to runner actions, we create a very extensible framework that is flexible enough to solve any user concerns in the future. By providing first party implementations, we give users easy starting points to customize specific hooks (like `docker build`) without having to write full blown solutions.
+
+The other would be to provide hooks that mirror every docker call we make, and expose more hooks to help support k8s users, with the expectation that users may have to no-op on multiple hooks if they don't correspond to our use case.
+
+Why we don't want to go that way
+- It feels clunky, users need to understand which hooks they need to implement and which they can ignore, which isn't a great UX
+- It doesn't scale well, I don't want to build a solution where we may need to add more hooks, by mapping to runner actions, updating hooks is a painful experience for users
+- Its overwhelming, its easier to tell users to build 4 hooks and track data themselves, rather then 16 hooks where the runner needs certain information and then needs to provide that information back into each hook. If we expose `Container Create`, you need to return the container you created, then we do `container run` which uses that container. If we just give you an image and say create and run this container, you don't need to store the container id in the runner, and it maps better to k8s scenarios where we don't really have container ids.
+
+### Prepare_job hook
+The `prepare_job` hook is called when a job is started. We pass in any job or service containers the job has. We expect that you:
+- Prune anything from previous jobs if needed
+- Create a network if needed
+- Pull the job and service containers
+- Start the job container
+- Start the service containers
+- Write to the response file some information we need
+  - Required: if the container is alpine, otherwise x64
+  - Optional: any context fields you want to set on the job context, otherwise they will be unavailable for users to use
+- Return 0 when the health checks have succeeded and the job/service containers are started
+
+This hook will **always** be called if you have container hooks enabled, even if no service or job containers exist in the job. This allows you to fail the job or implement a default job container if you want to and no job container has been provided.

+## Limitations
+- We will only support linux on launch
+- Hooks are set by the runner admin, and thus are only supported on self hosted runners 
+
+## Consequences
+- We support non docker scenarios for self hosted runners and allow customers to customize their docker invocations
+- We ship/maintain docs on docker hooks and an open source repo with examples
+- We support these hooks and add enough telemetry to be able to troubleshoot support issues as they come in.

+# ADR 2494: Runner Image Tags
+
+**Date**: 2023-03-17
+
+**Status**: Accepted<!-- |Accepted|Rejected|Superceded|Deprecated -->
+
+## Context
+
+Following the [adoption of actions-runner-controller by GitHub](https://github.com/actions/actions-runner-controller/discussions/2072) and the introduction of the new runner scale set autoscaling mode, we needed to provide a basic runner image that could be used off the shelf without much friction.
+
+The [current runner image](https://github.com/actions/runner/pkgs/container/actions-runner) is published to GHCR. Each release of this image is tagged with the runner version and the most recent release is also tagged with `latest`.
+
+While the use of `latest` is common practice, we recommend that users pin a specific version of the runner image for a predictable runtime and improved security posture. However, we still notice that a large number of end users are relying on the `latest` tag & raising issues when they encounter problems.
+
+Add to that, the community actions-runner-controller maintainers have issued a [deprecation notice](https://github.com/actions/actions-runner-controller/issues/2056) of the `latest` tag for the existing runner images (https://github.com/orgs/actions-runner-controller/packages).
+
+## Decision
+
+Proceed with Option 2, keeping the `latest` tag and adding the `NOTES.txt` file to our helm charts with the notice.
+
+### Option 1: Remove the `latest` tag
+
+By removing the `latest` tag, we have to proceed with either of these options:
+
+1. Remove the runner image reference in the `values.yaml` provided with the `gha-runner-scale-set` helm chart and mark these fields as required so that users have to explicitly specify a runner image and a specific tag. This will obviously introduce more  friction for users who want to start using actions-runner-controller for the first time.
+
+```yaml
+  spec:
+    containers:
+    - name: runner
+      image: ""
+      tag: ""
+      command: ["/home/runner/run.sh"]
+```
+
+1. Pin a specific runner image tag in the `values.yaml` provided with the `gha-runner-scale-set` helm chart. This will reduce friction for users who want to start using actions-runner-controller for the first time but will require us to update the `values.yaml` with every new runner release.
+
+```yaml
+  spec:
+    containers:
+    - name: runner
+      image: "ghcr.io/actions/actions-runner"
+      tag: "v2.300.0"
+      command: ["/home/runner/run.sh"]
+```
+
+### Option 2: Keep the `latest` tag
+
+Keeping the `latest` tag is also a reasonable option especially if we don't expect to make any breaking changes to the runner image. We could enhance this by adding a [NOTES.txt](https://helm.sh/docs/chart_template_guide/notes_files/) to the helm chart which will be displayed to the user after a successful helm install/upgrade. This will help users understand the implications of using the `latest` tag and how to pin a specific version of the runner image.
+
+The runner image release workflow will need to be updated so that the image is pushed to GHCR and tagged only when the runner rollout has reached all scale units.
+
+## Consequences
+
+Proceeding with **option 1** means:
+
+1. We will enhance the runtime predictability and security posture of our end users
+1. We will have to update the `values.yaml` with every new runner release (that can be automated)
+1. We will introduce friction for users who want to start using actions-runner-controller for the first time
+
+Proceeding with **option 2** means:
+
+1. We will have to continue to maintain the `latest` tag
+1. We will assume that end users will be able to handle the implications of using the `latest` tag
+1. Runner image release workflow needs to be updated

+# Actions Connection Check
+
+## What is this check for?
+
+Make sure the runner has access to actions service for GitHub.com or GitHub Enterprise Server
+
+- For GitHub.com
+  - The runner needs to access `https://api.github.com` for downloading actions.
+  - The runner needs to access `https://codeload.github.com` for downloading actions tar.gz/zip.
+  - The runner needs to access `https://vstoken.actions.githubusercontent.com/_apis/.../` for requesting an access token.
+  - The runner needs to access `https://pipelines.actions.githubusercontent.com/_apis/.../` for receiving workflow jobs.
+  - The runner needs to access `https://results-receiver.actions.githubusercontent.com/.../` for reporting progress and uploading logs during a workflow job execution.
+  ---
+  **NOTE:** for the full list of domains that are required to be in the firewall allow list refer to the [GitHub self-hosted runners requirements documentation](https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners/about-self-hosted-runners#communication-between-self-hosted-runners-and-github).
+
+  These can by tested by running the following `curl` commands from your self-hosted runner machine:
+
+    ```
+    curl -v https://api.github.com/zen
+    curl -v https://codeload.github.com/_ping
+    curl -v https://vstoken.actions.githubusercontent.com/_apis/health
+    curl -v https://pipelines.actions.githubusercontent.com/_apis/health
+    curl -v https://results-receiver.actions.githubusercontent.com/health
+    ```
+
+- For GitHub Enterprise Server
+  - The runner needs to access `https://[hostname]/api/v3` for downloading actions.
+  - The runner needs to access `https://codeload.[hostname]/_ping` for downloading actions tar.gz/zip.
+  - The runner needs to access `https://[hostname]/_services/vstoken/_apis/.../` for requesting an access token.
+  - The runner needs to access `https://[hostname]/_services/pipelines/_apis/.../` for receiving workflow jobs.
+  
+  These can by tested by running the following `curl` commands from your self-hosted runner machine, replacing `[hostname]` with the hostname of your appliance, for instance `github.example.com`:
+
+    ```
+    curl -v https://[hostname]/api/v3/zen
+    curl -v https://codeload.[hostname]/_ping
+    curl -v https://[hostname]/_services/vstoken/_apis/health
+    curl -v https://[hostname]/_services/pipelines/_apis/health
+    ```
+
+    A common cause of this these connectivity issues is if your to GitHub Enterprise Server appliance is using [the self-signed certificate that is enabled the first time](https://docs.github.com/en/enterprise-server/admin/configuration/configuring-network-settings/configuring-tls) your appliance is started. As self-signed certificates are not trusted by web browsers and Git clients, these clients (including the GitHub Actions runner) will report certificate warnings.
+    
+    We recommend [upload a certificate signed by a trusted authority](https://docs.github.com/en/enterprise-server/admin/configuration/configuring-network-settings/configuring-tls) to GitHub Enterprise Server, or enabling the built-in ][Let's Encrypt support](https://docs.github.com/en/enterprise-server/admin/configuration/configuring-network-settings/configuring-tls).

+# Git Connection Check
+
+## What is this check for?
+
+Make sure `git` can access GitHub.com or your GitHub Enterprise Server.
+
+
+## What is checked?
+
+The test is done by executing
+```bash
+# For GitHub.com
+git ls-remote --exit-code https://github.com/actions/checkout HEAD
+
+# For GitHub Enterprise Server
+git ls-remote --exit-code https://ghes.me/actions/checkout HEAD
+```
+
+The test also set environment variable `GIT_TRACE=1` and `GIT_CURL_VERBOSE=1` before running `git ls-remote`, this will make `git` to produce debug log for better debug any potential issues.
+
+## How to fix the issue?
+
+### 1. Check global and system git config
+
+If you are having issues connecting to the server, check your global and system git config for any unexpected authentication headers. You might be seeing an error like:
+
+```
+fatal: unable to access 'https://github.com/actions/checkout/': The requested URL returned error: 400
+```
+
+The following commands can be used to check for unexpected authentication headers:
+
+```
+$ git config --global --list | grep extraheader
+http.extraheader=AUTHORIZATION: unexpected_auth_header
+
+$ git config --system --list | grep extraheader
+```
+
+The following command can be used to remove the above value: `git config --global --unset http.extraheader`
+
+### 2. Check the common network issue
+  
+  > Please check the [network doc](./network.md)
+
+### 3. SSL certificate related issue
+
+  If you are seeing `SSL Certificate problem:` in the log, it means the `git` can't connect to the GitHub server due to SSL handshake failure.

+## Common Network Related Issues
+
+### Common things that can cause the runner to not working properly
+
+- A bug in the runner or the dotnet framework that causes the actions runner to be unable to make Http requests in a certain network environment.
+
+- A Proxy or Firewall may block certain HTTP method, such as blocking all POST and PUT calls which the runner will use to upload logs.
+
+- A Proxy or Firewall may only allows requests with certain user-agent to pass through and the actions runner user-agent is not in the allow list.
+
+- A Proxy try to decrypt and exam HTTPS traffic for security purpose but cause the actions-runner to fail to finish SSL handshake due to the lack of trusting proxy's CA.
+
+- The SSL handshake may fail if the client and server do not support the same TLS version, or the same cipher suites.
+
+- A Proxy may try to modify the HTTPS request (like add or change some http headers) and causes the request become incompatible with the Actions Service (ASP.NetCore), Ex: [Nginx](https://github.com/dotnet/aspnetcore/issues/17081)
+
+- Firewall rules that block action runner from accessing [certain hosts](https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners/about-self-hosted-runners#communication-between-self-hosted-runners-and-github), ex: `*.github.com`, `*.actions.githubusercontent.com`, etc
+
+
+### Identify and solve these problems
+
+The key is to figure out where is the problem, the network environment, or the actions runner?
+
+Use a 3rd party tool to make the same requests as the runner did would be a good start point.
+
+- Use `nslookup` to check DNS
+- Use `ping` to check Ping
+- Use `traceroute`, `tracepath`, or `tracert` to check the network route between the runner and the Actions service
+- Use `curl -v` to check the network stack, good for verifying default certificate/proxy settings.
+- Use `Invoke-WebRequest` from `pwsh` (`PowerShell Core`) to check the dotnet network stack, good for verifying bugs in the dotnet framework.
+
+If the 3rd party tool is also experiencing the same error as the runner does, then you might want to contact your network administrator for help.
+
+Otherwise, contact GitHub customer support or log an issue at https://github.com/actions/runner
+
+### Troubleshooting: Why can't I configure a runner?
+
+If you are having trouble connecting, try these steps:
+
+1. Validate you can reach our endpoints from your web browser. If not, double check your local network connection
+    - For hosted Github:
+      - https://api.github.com/
+      - https://vstoken.actions.githubusercontent.com/_apis/health
+      - https://pipelines.actions.githubusercontent.com/_apis/health
+      - https://results-receiver.actions.githubusercontent.com/health
+    - For GHES/GHAE
+      - https://myGHES.com/_services/vstoken/_apis/health
+      - https://myGHES.com/_services/pipelines/_apis/health
+      - https://myGHES.com/api/v3
+2. Validate you can reach those endpoints in powershell core
+    - The runner runs on .net core, lets validate the local settings for that stack
+    - Open up `pwsh`
+    - Run the command using the urls above `Invoke-WebRequest {url}`
+3. If not, get a packet trace using a tool like wireshark and start looking at the TLS handshake.
+    - If you see a Client Hello followed by a Server RST:
+      - You may need to configure your TLS settings to use the correct version
+        - You should support TLS version 1.2 or later
+      - You may need to configure your TLS settings to have up to date cipher suites, this may be solved by system updates and patches.

+# Node.js Connection Check
+
+## What is this check for?
+
+Make sure the built-in node.js has access to GitHub.com or GitHub Enterprise Server.
+
+The runner carries its own copies of node.js executables under `<runner_root>/externals/node20/` and `<runner_root>/externals/node24/`.
+
+All javascript base Actions will get executed by the built-in `node` at either `<runner_root>/externals/node20/` or `<runner_root>/externals/node24/` depending on the version specified in the action's metadata.
+
+> Not the `node` from `$PATH`
+
+## What is checked?
+
+- Make HTTPS GET to https://api.github.com or https://myGHES.com/api/v3 using node.js, make sure it gets 200 response code.
+
+## How to fix the issue?
+
+### 1. Check the common network issue
+  
+  > Please check the [network doc](./network.md)
+
+### 2. SSL certificate related issue
+
+  If you are seeing `Https request failed due to SSL cert issue` in the log, it means the `node.js` can't connect to the GitHub server due to SSL handshake failure.
+  > Please check the [SSL cert doc](./sslcert.md)
+  
+## Still not working?
+
+Contact GitHub customer service or log an issue at https://github.com/actions/runner if you think it's a runner issue.

+## SSL Certificate Related Issues
+
+You might run into an SSL certificate error when your GitHub Enterprise Server is using a self-signed SSL server certificate or a web proxy within your network is decrypting HTTPS traffic for a security audit.
+
+As long as your certificate is generated properly, most of the issues should be fixed after your trust the certificate properly on the runner machine.
+
+> Different OS might have extra requirements on SSL certificate,
+> Ex: macOS requires `ExtendedKeyUsage` https://support.apple.com/en-us/HT210176
+
+### Don't skip SSL cert validation
+
+> !!! DO NOT SKIP SSL CERT VALIDATION !!!  
+> !!! IT IS A BAD SECURITY PRACTICE !!!  
+
+### Download SSL certificate chain
+
+Depends on how your SSL server certificate gets configured, you might need to download the whole certificate chain from a machine that has trusted the SSL certificate's CA.
+
+- Approach 1: Download certificate chain using a browser (Chrome, Firefox, IT), you can google for more example, [here is what I found](https://medium.com/@menakajain/export-download-ssl-certificate-from-server-site-url-bcfc41ea46a2)
+
+- Approach 2: Download certificate chain using OpenSSL, you can google for more example, [here is what I found](https://superuser.com/a/176721)
+
+- Approach 3: Ask your network administrator or the owner of the CA certificate to send you a copy of it
+
+### Trust CA certificate for the Runner
+
+The actions runner is a dotnet core application which will follow how dotnet load SSL CA certificates on each OS.
+
+You can get full details documentation at [here](https://docs.microsoft.com/en-us/dotnet/standard/security/cross-platform-cryptography#x509store)
+
+In short:
+- Windows: Load from Windows certificate store.
+- Linux: Load from OpenSSL CA cert bundle.
+- macOS: Load from macOS KeyChain.
+
+To let the runner trusts your CA certificate, you will need to:
+1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
+2. Use `OpenSSL` to convert `.pem` file to a proper format for different OS, here is some [doc with sample commands](https://www.sslshopper.com/ssl-converter.html)
+3. Trust CA on different OS:
+    - Windows: https://docs.microsoft.com/en-us/skype-sdk/sdn/articles/installing-the-trusted-root-certificate
+    - macOS: ![trust ca cert](./../res/macOStrustCA.gif)
+    - Linux: Refer to the distribution documentation
+      1. RedHat: https://www.redhat.com/sysadmin/ca-certificates-cli
+      2. Ubuntu: http://manpages.ubuntu.com/manpages/focal/man8/update-ca-certificates.8.html
+      3. Google search: "trust ca certificate on [linux distribution]"
+      4. If all approaches failed, set environment variable `SSL_CERT_FILE` to the CA bundle `.pem` file we get.
+    > To verify cert gets installed properly on Linux, you can try use `curl -v https://sitewithsslissue.com` and `pwsh -Command \"Invoke-WebRequest -Uri https://sitewithsslissue.com\"`
+
+### Trust CA certificate for Git CLI
+
+Git uses various CA bundle file depends on your operation system.
+- Git packaged the CA bundle file within the Git installation on Windows
+- Git use OpenSSL certificate CA bundle file on Linux and macOS
+
+You can check where Git check CA file by running:
+```bash
+export GIT_CURL_VERBOSE=1
+git ls-remote https://github.com/actions/runner HEAD
+```
+
+You should see something like:
+```
+* Couldn't find host github.com in the .netrc file; using defaults
+*   Trying 140.82.114.4...
+* TCP_NODELAY set
+* Connected to github.com (140.82.114.4) port 443 (#0)
+* ALPN, offering h2
+* ALPN, offering http/1.1
+* successfully set certificate verify locations:
+*   CAfile: /etc/ssl/cert.pem
+  CApath: none
+* SSL connection using TLSv1.2 / ECDHE-RSA-AES128-GCM-SHA256
+```
+This tells me `/etc/ssl/cert.pem` is where it read trusted CA certificates.
+
+To let Git trusts your CA certificate, you will need to:
+1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
+2. Set `http.sslCAInfo` Git config or `GIT_SSL_CAINFO` environment variable to the full path of the `.pem` file [Git Doc](https://git-scm.com/docs/git-config#Documentation/git-config.txt-httpsslCAInfo)
+> I would recommend using `http.sslCAInfo` since it can be scope to certain hosts that need the extra trusted CA.  
+> Ex: `git config --global http.https://myghes.com/.sslCAInfo /extra/ca/cert.pem`  
+> This will make Git use the `/extra/ca/cert.pem` only when communicates with `https://myghes.com` and keep using the default CA bundle with others.
+
+### Trust CA certificate for Node.js
+
+Node.js has compiled a snapshot of the Mozilla CA store that is fixed at each version of Node.js' release time.
+
+To let Node.js trusts your CA certificate, you will need to:
+1. Save your SSL certificate chain which includes the root CA and all intermediate CAs into a `.pem` file.
+2. Set environment variable `NODE_EXTRA_CA_CERTS` which point to the file. ex: `export NODE_EXTRA_CA_CERTS=/full/path/to/cacert.pem` or `set NODE_EXTRA_CA_CERTS=C:\full\path\to\cacert.pem`

+## Quickstart: Run a job from a real repository
+
+If you just want to get from building the sourcecode to using it to execute an action, you will need:
+
+- The url of your repository
+- A runner registration token. You can find it at `https://github.com/{your-repo}/settings/actions/runners/new`
+
+
+```bash
+git clone https://github.com/actions/runner
+cd runner/src
+./dev.(sh/cmd) layout # the runner that built from source is in {root}/_layout
+cd ../_layout
+./config.(sh/cmd) --url https://github.com/{your-repo} --token ABCABCABCABCABCABCABCABCABCAB # accept default name, labels and work folder
+./run.(sh/cmd)
+```
+
+If you trigger a job now, you can see the runner execute it.
+
+Tip: Make sure your job can run on this runner. The easiest way is to set `runs-on: self-hosted` in the workflow file.
+

+git clone https://github.com/actions/runner
+cd runner
+```
+If you want to push your changes to a remote, it is recommended you fork the repository and use that fork as your origin instead of `https://github.com/actions/runner`.
+
+
+### Build Layout:
+
+This command will build all projects, then copies them and other dependencies into a folder called `_layout`. The binaries in this folder are then used for running, debugging the runner.
+
+```bash
+cd ./src # execute the script from this folder
+./dev.(sh/cmd) layout # the runner that built from source is in {root}/_layout
+```
+
+If you make code changes after this point, use the argument `build` to build your code in the `src` folder to keep your `_layout` folder up to date.
+
+```bash
+cd ./src
+./dev.(sh/cmd) build # {root}/_layout will get updated

+# Development Life Cycle using VS Code:
+
+These examples use VS Code, but the idea should be similar across all IDEs as long as you attach to the same processes in the right folder.
+## Configure
+
+To successfully start the runner, you need to register it using a repository and a runner registration token.
+Run `Configure` first to build the source code and set up the runner in `_layout`.
+Once it's done creating `_layout`, it asks for the url of your repository and your token in the terminal.
+
+Check [Quickstart](../contribute.md#quickstart-run-a-job-from-a-real-repository) if you don't know how to get this token.
+
+## Debugging
+
+Debugging the full lifecycle of a job can be tricky, because there are multiple processes involved.
+All the configs below can be found in `.vscode/launch.json`.
+
+## Debug the Listener
+
+```json
+{
+    "name": "Run [build]",
+    "type": "coreclr",
+    "request": "launch",
+    "preLaunchTask": "build runner layout",  // use the config called "Run" to launch without rebuild
+    "program": "${workspaceFolder}/_layout/bin/Runner.Listener",
+    "args": [
+        "run" // run without args to print usage
+    ],
+    "cwd": "${workspaceFolder}/src",
+    "console": "integratedTerminal",
+    "requireExactSource": false,
+}
+```
+
+If you launch `Run` or `Run [build]`, it starts a process called `Runner.Listener`.
+This process will receive any job queued on this repository if the job runs on matching labels (e.g `runs-on: self-hosted`).
+Once a job is received, a `Runner.Listener` starts a new process of `Runner.Worker`.
+Since this is a different process, you can't use the same debugger session debug it.
+Instead, a parallel debugging session has to be started, using a different launch config.
+Luckily, VS Code supports multiple parallel debugging sessions.
+
+## Debug the Worker
+
+Because the worker process is usually started by the listener instead of an IDE, debugging it from start to finish can be tricky.
+For this reason, `Runner.Worker` can be configured to wait for a debugger to be attached before it begins any actual work.
+
+Set the environment variable `GITHUB_ACTIONS_RUNNER_ATTACH_DEBUGGER` to `true` or `1` to enable this wait.
+All worker processes now will wait 20 seconds before they start working on their task.
+
+This gives enough time to attach a debugger by running `Debug Worker`.
+If for some reason you have multiple workers running, run the launch config `Attach` instead.
+Select `Runner.Worker` from the running processes when VS Code prompts for it.

+We recommend configuring the runner in a root folder of the Windows drive (e.g. "C:\actions-runner"). This will help avoid issues related to service identity folder permissions and long file path restrictions on Windows.
+
+The following snipped needs to be run on `powershell`:
+
+```powershell
+# Create a folder under the drive root
+mkdir \actions-runner ; cd \actions-runner
+# Download the latest runner package
+Invoke-WebRequest -Uri https://github.com/actions/runner/releases/download/v<RUNNER_VERSION>/actions-runner-win-arm64-<RUNNER_VERSION>.zip -OutFile actions-runner-win-arm64-<RUNNER_VERSION>.zip
