+## 🚀 Release Process
+
+> **For core team maintainers only.** Community members do not participate in releasing.
+
+Releases are triggered manually by a core team member using the GitHub Actions release workflow.
+
+### Steps
+
+1. **Launch the release action**
+
+   Go to [Actions → Release](https://github.com/github/gh-aw/actions/workflows/release.lock.yml) and click **Run workflow**. Select the release type (`patch`, `minor`, or `major`) and start the run.
+
+   The workflow will build the release binaries, push a new git tag, and then pause — waiting for a required manual step before publishing.
+
+2. **Complete the sync in `github/gh-aw-actions`**
+
+   While the workflow is paused at the `gh-aw-actions-release` environment gate, complete the following steps in the [`github/gh-aw-actions`](https://github.com/github/gh-aw-actions) repository:
+
+   a. **Run the sync-actions workflow** — go to [Actions → sync-actions](https://github.com/github/gh-aw-actions/actions/workflows/sync-actions.yml) and trigger it with the new release tag (e.g. `v1.2.3`).
+
+   b. **Merge the PR** — the sync-actions workflow will open a pull request in `github/gh-aw-actions`. Review and merge it to bring the tag into that repository.
+
+3. **Approve the environment gate**
+
+   Return to the paused release run in [`github/gh-aw`](https://github.com/github/gh-aw/actions). Approve the **`gh-aw-actions-release`** environment gate. The workflow will verify that the new tag exists in `github/gh-aw-actions` and then publish the GitHub release.
