 - Keep your change as focused as possible. If there are multiple changes you would like to make that are not dependent upon each other, consider submitting them as separate pull requests.

+## Releasing (write access required)
+
+1. The first step of releasing a new version of the `codeql-action` is running the "Update release branch" workflow.
+    This workflow goes through the pull requests that have been merged to `main` since the last release, creates a changelog, then opens a pull request to merge the changes since the last release into the `v1` release branch.
+
+    A release is automatically started every Monday via a scheduled run of this workflow, however you can start a release manually by triggering a run via [workflow dispatch](https://github.com/github/codeql-action/actions/workflows/update-release-branch.yml). 
+1. The workflow run will open a pull request titled "Merge main into v1". Mark the pull request as [ready for review](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/changing-the-stage-of-a-pull-request#marking-a-pull-request-as-ready-for-review) to trigger the PR checks.
+1. Review the checklist items in the pull request description.
+    Once you've checked off all but the last of these, approve the PR and automerge it.
+1. When the "Merge main into v1" pull request is merged into the `v1` branch, the "Tag release and merge back" workflow will create a mergeback PR.
+    This mergeback incorporates the changelog updates into `main`, tags the release using the merge commit of the "Merge main into v1" pull request, and bumps the patch version of the CodeQL Action.
+
+    Approve the mergeback PR and automerge it. Once the mergeback has been merged into main, the release is complete.
