+# Release Process
+
+> [!NOTE]
+> Before starting, let Michael McLoughlin know that a release is about to be created so that documentation can be prepared in advance.
+
+The release process is semi-automated.
+
+### Step 1: Git Tag and GitHub Release
+
+> [!NOTE]
+>
+> Upon pushing the tag, a GitHub Action will do the following:
+> - Build and publish the container image at `quay.io/jetstack/venafi-agent`,
+> - Build and publish the Helm chart at `oci://quay.io/jetstack/charts/venafi-kubernetes-agent`,
+> - Create a draft GitHub release,
+> - Upload the Helm chart tarball to the GitHub release.
+
+1. Open the [tests GitHub Actions workflow][tests-workflow]
+   and verify that it succeeds on the master branch.
+
+2. Run govulncheck:
+   ```bash
+   go install golang.org/x/vuln/cmd/govulncheck@latest
+   govulncheck -v ./...
+   ```
+
+3. Create a tag for the new release:
+   ```sh
+   export VERSION=v1.1.0
+   git tag --annotate --message="Release ${VERSION}" "${VERSION}"
+   git push origin "${VERSION}"
+   ```
+
+4. Wait until the GitHub Actions finishes.
+
+5. Navigate to the GitHub Releases page and select the draft release to edit.
+   1. Click on “Generate release notes” to automatically compile the changelog.
+   2. Review and refine the generated notes to ensure they’re clear and useful
+      for end users.
+   3. Remove any irrelevant entries, such as “update deps,” “update CI,” “update
+      docs,” or similar internal changes that do not impact user functionality.
+
+6. Publish the release.
+
+7. Inform the `#venctl` channel that a new version of Venafi Kubernetes Agent has been
+   released. Make sure to share any breaking change that may affect `venctl connect`
+   or `venctl generate`.
+
+8. Inform Michael McLoughlin of the new release so he can update the
+   documentation at <https://docs.venafi.cloud/>.
