 [![Actions Status](https://github.com/actions/runner/workflows/Runner%20CI/badge.svg)](https://github.com/actions/runner/actions)
 
+The runner is the application that runs a job from a GitHub Actions workflow.  The runner can run on the [hosted machine pools](https://github.com/actions/virtual-environments) or run on [self-hosted environments](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners).
+
 ## Get Started

+# ADR 263: Self Hosted Runner Proxies
+**Date**: 2019-11-13
+
+**Status**: Accepted
+
+## Context
+
+- Proxy support is required for some enterprises and organizations to start using their own self hosted runners
+- While there is not a standard convention, many applications support setting proxies via the environmental variables `http_proxy`, `https_proxy`, `no_proxy`, such as curl, wget, perl, python, docker, git, R, ect
+  - Some of these applications use `HTTPS_PROXY` versus `https_proxy`, but most understand or primarily support the lowercase variant
+
+
+## Decisions
+
+We will update the Runner to use the conventional environment variables for proxies: `http_proxy`, `https_proxy` and `no_proxy` if they are set.
+These are described in detail below:
+- `https_proxy` a proxy URL for all https traffic. It may contain basic authentication credentials. For example:
+  - http://proxy.com
+  - http://127.0.0.1:8080
+  - http://user:password@proxy.com
+- `http_proxy` a proxy URL for all http traffic. It may contain basic authentication credentials. For example:
+  - http://proxy.com
+  - http://127.0.0.1:8080
+  - http://user:password@proxy.com
+- `no_proxy` a comma seperated list of hosts that should not use the proxy. An optional port may be specified
+  - `google.com`
+  - `yahoo.com:443`
+  - `google.com,bing.com`
+
+We won't use `http_proxy` for https traffic when `https_proxy` is not set, this behavior lines up with any libcurl based tools (curl, git) and wget.
+Otherwise action authors and workflow users need to adjust to differences between the runner proxy convention, and tools used by their actions and scripts.  
+
+Example:  
+  Customer set `http_proxy=http://127.0.0.1:8888` and configure the runner against `https://github.com/owner/repo`, with the `https_proxy` -> `http_proxy` fallback, the runner will connect to server without any problem. However, if user runs `git push` to `https://github.com/owner/repo`, `git` won't use the proxy since it require `https_proxy` to be set for any https traffic.
+
+> `golang`, `node.js` and other dev tools from the linux community use `http_proxy` for both http and https traffic base on my research.
+
+A majority of our users are using Linux where these variables are commonly required to be set by various programs. By reading these values, we simplify the process for self hosted runners to set up proxy, and expose it in a way users are already familiar with.
+
+A password provided for a proxy will be masked in the logs.
+
+We will support the lowercase and uppercase variants, with lowercase taking priority if both are set.
+
+### No Proxy Format
+
+While exact implementations are different per application on handle `no_proxy` env, most applications accept a comma separated list of hosts. Some accept wildcard characters (*). We are going to do exact case-insentive matches, and not support wildcards at this time.
+For example:
+- example.com will match example.com, foo.example.com, foo.bar.example.com
+- foo.example.com will match bar.foo.example.com and foo.example.com
+
+We will not support IP addresses for `no_proxy`, only hostnames.
+
+## Consequences
+
+1. Enterprises and organizations needing proxy support will be able to embrace self hosted runners
+2. Users will need to set these environmental variables before configuring the runner in order to use a proxy when configuring
+3. The runner will read from the environmental variables during config and runtime and use the provided proxy if it exists
+4. Users may need to pass these environmental variables into other applications if they do not natively take these variables
+5. Action authors may need to update their workflows to react to the these environment variables
+6. We will document the way of setting environmental variables for runners using the environmental variables and how the runner uses them
+7. Like all other secrets, users will be able to relatively easily figure out proxy password if they can modify a workflow file running on a self hosted machine

+# ADRs
+
+ADR, short for "Architecture Decision Record" is a way of capturing important architectural decisions, along with their context and consequences.
+
+This folder includes ADRs for the actions runner. ADRs are proposed in the form of a pull request, and they commonly follow this format:
+
+* **Title**: short present tense imperative phrase, less than 50 characters, like a git commit message.
+
+* **Status**: proposed, accepted, rejected, deprecated, superseded, etc.
+
+* **Context**: what is the issue that we're seeing that is motivating this decision or change.
+
+* **Decision**: what is the change that we're actually proposing or doing.
+
+* **Consequences**: what becomes easier or more difficult to do because of this change.

+# Contributions
 
-## Dev Dependencies
+We welcome contributions in the form of issues and pull requests.  We view the contributions and the process as the same for github and external contributors.
+
+> IMPORTANT: Building your own runner is critical for the dev inner loop process when contributing changes.  However, only runners built and distributed by GitHub (releases) are supported in production.  Be aware that workflows and orchestrations run service side with the runner being a remote process to run steps.  For that reason, the service can pull the runner forward so customizations can be lost.
+
+## Issues
+
+Log issues for both bugs and enhancement requests.  Logging issues are important for the open community.
+
+Issues in this repository should be for the runner application.  Note that the VM and virtual machine images (including the developer toolsets) installed on the actions hosted machine pools are located [in this repository](https://github.com/actions/virtual-environments)
+
+## Enhancements and Feature Requests
+
+We ask that before significant effort is put into code changes, that we have agreement on taking the change before time is invested in code changes. 
+
+1. Create a feature request.  Once agreed we will take the enhancment
+2. Create an ADR to agree on the details of the change.
+
+An ADR is an Architectural Decision Record.  This allows consensus on the direction forward and also serves as a record of the change and motivation.  [Read more here](adrs/README.md)

 You can easily correct the problem by executing `./bin/installdependencies.sh`.  
 The `installdependencies.sh` script should install all required dependencies on all supported Linux versions
