+# Release Note Template
+
+This is the template of actions-runner-controller's release notes.
+
+Whenever a new release is made, I start by manually copy-pasting this template onto the GitHub UI for creating the release.
+
+I then walk-through all the changes, take sometime to think abount best one-sentence explanations to tell the users about changes, write it all,
+and click the publish button.
+
+If you think you can improve future release notes in any way, please do submit a pull request to change the template below.
+
+Note that even though it looks like a Go template, I don't use any templating to generate the changelog.
+It's just that I'm used to reading and intepreting Go template by myself, not a computer program :)
+
+**Title**:
+
+```
+v{{ .Version }}: {{ .TitlesOfImportantChanges }}
+```
+
+**Body**:
+
+```
+**CAUTION:** If you're using the Helm chart, beware to review changes to CRDs and do manually upgrade CRDs! Helm installs CRDs only on installing a chart. It doesn't automatically upgrade CRDs. Otherwise you end up with troubles like #427, #467, and #468. Please refer to the [UPGRADING](charts/actions-runner-controller/docs/UPGRADING.md) docs for the latest process.

+## Contributing
+
+### How to Contribute a Patch
+
+Depending on what you are patching depends on how you should go about it. Below are some guides on how to test patches locally as well as develop the controller and runners.
+
+When sumitting a PR for a change please provide evidence that your change works as we still need to work on improving the CI of the project. Some resources are provided for helping achieve this, see this guide for details.
+
+#### Running an End to End Test
+
+> **Notes for Ubuntu 20.04+ users**
+>
+> If you're using Ubuntu 20.04 or greater, you might have installed `docker` with `snap`.
+>
+> If you want to stick with `snap`-provided `docker`, do not forget to set `TMPDIR` to
+> somewhere under `$HOME`.
+> Otherwise `kind load docker-image` fail while running `docker save`.
+> See https://kind.sigs.k8s.io/docs/user/known-issues/#docker-installed-with-snap for more information.
+
+To test your local changes against both PAT and App based authentication please run the `acceptance` make target with the authentication configuration details provided:
+
+```shell
+# This sets `VERSION` envvar to some appropriate value
+. hack/make-env.sh
+
+DOCKER_USER=*** \
+  GITHUB_TOKEN=*** \
+  APP_ID=*** \
+  PRIVATE_KEY_FILE_PATH=path/to/pem/file \
+  INSTALLATION_ID=*** \
+  make acceptance
+```
+
+**Rerunning a failed test**
+
+When one of tests run by `make acceptance` failed, you'd probably like to rerun only the failed one.
+
+It can be done by `make acceptance/run` and by setting the combination of `ACCEPTANCE_TEST_DEPLOYMENT_TOOL=helm|kubectl` and `ACCEPTANCE_TEST_SECRET_TYPE=token|app` values that failed (note, you just need to set the corresponding authentication configuration in this circumstance)
+
+In the example below, we rerun the test for the combination `ACCEPTANCE_TEST_DEPLOYMENT_TOOL=helm ACCEPTANCE_TEST_SECRET_TYPE=token` only:
+
+```shell
+DOCKER_USER=*** \
+  GITHUB_TOKEN=*** \
+  ACCEPTANCE_TEST_DEPLOYMENT_TOOL=helm
+  ACCEPTANCE_TEST_SECRET_TYPE=token \
+  make acceptance/run
+```
+
+**Testing in a non-kind cluster**
+
+If you prefer to test in a non-kind cluster, you can instead run:
+
+```shell
+KUBECONFIG=path/to/kubeconfig \
+  DOCKER_USER=*** \
+  GITHUB_TOKEN=*** \
+  APP_ID=*** \
+  PRIVATE_KEY_FILE_PATH=path/to/pem/file \
+  INSTALLATION_ID=*** \
+  ACCEPTANCE_TEST_SECRET_TYPE=token \
+  make docker-build acceptance/setup \
+       acceptance/deploy \
+       acceptance/tests
+```
+
+#### Developing the Controller
+
+Rerunning the whole acceptance test suite from scratch on every little change to the controller, the runner, and the chart would be counter-productive.
+
+To make your development cycle faster, use the below command to update deploy and update all the three:
+
+```shell
+# Let assume we have all other envvars like DOCKER_USER, GITHUB_TOKEN already set,
+# The below command will (re)build `actions-runner-controller:controller1` and `actions-runner:runner1`,
+# load those into kind nodes, and then rerun kubectl or helm to install/upgrade the controller,
+# and finally upgrade the runner deployment to use the new runner image.
+#
+# As helm 3 and kubectl is unable to recreate a pod when no tag change,
+# you either need to bump VERSION and RUNNER_TAG on each run,
+# or manually run `kubectl delete pod $POD` on respective pods for changes to actually take effect.
+
+VERSION=controller1 \
+  RUNNER_TAG=runner1 \
+  make acceptance/pull acceptance/kind docker-build acceptance/load acceptance/deploy
+```
+
+If you've already deployed actions-runner-controller and only want to recreate pods to use the newer image, you can run:
+
+```shell
+NAME=$DOCKER_USER/actions-runner-controller \
+  make docker-build acceptance/load && \
+  kubectl -n actions-runner-system delete po $(kubectl -n actions-runner-system get po -ojsonpath={.items[*].metadata.name})
+```
+
+Similarly, if you'd like to recreate runner pods with the newer runner image,
+
+```shell
+NAME=$DOCKER_USER/actions-runner make \
+  -C runner docker-{build,push}-ubuntu && \
+  (kubectl get po -ojsonpath={.items[*].metadata.name} | xargs -n1 kubectl delete po)
+```
+
+#### Developing the Runners
+
+**Tests**
+
+A set of example pipelines (./acceptance/pipelines) are provided in this repository which you can use to validate your runners are working as expected. When raising a PR please run the relevant suites to prove your change hasn't broken anything.
+
+**Running Ginkgo Tests**
+
+You can run the integration test suite that is written in Ginkgo with:
+
+```shell
+make test-with-deps
+```
+
+This will firstly install a few binaries required to setup the integration test environment and then runs `go test` to start the Ginkgo test.
+
+If you don't want to use `make`, like when you're running tests from your IDE, install required binaries to `/usr/local/kubebuilder/bin`. That's the directory in which controller-runtime's `envtest` framework locates the binaries.
+
+```shell
+sudo mkdir -p /usr/local/kubebuilder/bin
+make kube-apiserver etcd
+sudo mv test-assets/{etcd,kube-apiserver} /usr/local/kubebuilder/bin/
+go test -v -run TestAPIs github.com/actions-runner-controller/actions-runner-controller/controllers
+```
+
+To run Ginkgo tests selectively, set the pattern of target test names to `GINKGO_FOCUS`.
+All the Ginkgo test that matches `GINKGO_FOCUS` will be run.
+
+```shell
+GINKGO_FOCUS='[It] should create a new Runner resource from the specified template, add a another Runner on replicas increased, and removes all the replicas when set to 0' \
+  go test -v -run TestAPIs github.com/actions-runner-controller/actions-runner-controller/controllers
+```
+
+#### Helm Version Bumps
+
+**Chart Version :** When bumping the chart version follow semantic versioning https://semver.org/<br />
+**App Version :** When bumping the app version you will also need to bump the chart version too. Again, follow semantic versioning when bumping the chart.
+
+To determine if you need to bump the MAJOR, MINOR or PATCH versions you will need to review the changes between the previous app version and the new app version and / or ask for a maintainer to advise.

+## Upgrading
+
+This project makes extensive use of CRDs to provide much of its functionality. Helm unfortunately does not support [managing](https://helm.sh/docs/chart_best_practices/custom_resource_definitions/) CRDs by design:
+
+_The full breakdown as to how they came to this decision and why they have taken the approach they have for dealing with CRDs can be found in [Helm Improvement Proposal 11](https://github.com/helm/community/blob/main/hips/hip-0011.md)_
+
+```
+There is no support at this time for upgrading or deleting CRDs using Helm. This was an explicit decision after much 
+community discussion due to the danger for unintentional data loss. Furthermore, there is currently no community 
+consensus around how to handle CRDs and their lifecycle. As this evolves, Helm will add support for those use cases.
+```
+
+Helm will do an initial install of CRDs but it will not touch them afterwards (update or delete).
+
+Additionally, because the project leverages CRDs so extensively you **MUST** run the matching controller app container with its matching CRDs i.e. always redeploy your CRDs if you are changing the app version.
+
+Due to the above you can't just do a `helm upgrade` to release the latest version of the chart, the best practice steps are recorded below:
+
+## Steps
+
+1. Upgrade CRDs
+
+```shell
+ # REMEMBER TO UPDATE THE CHART_VERSION TO RELEVANT CHART VERISON!!!!
+CHART_VERSION=0.11.0
+
+curl -L https://github.com/actions-runner-controller/actions-runner-controller/releases/download/actions-runner-controller-${CHART_VERSION}/actions-runner-controller-${CHART_VERSION}.tgz | tar zxv --strip 1 actions-runner-controller/crds
+
+kubectl apply -f crds/
+```
+
+2. Upgrade the Helm release
+
+```shell
+helm upgrade --install \
+  --namespace actions-runner-system \
+  --version ${CHART_VERSION} \
+  actions-runner-controller/actions-runner-controller \
+  actions-runner-controller
+```
