+
+How to perform a release of the plugin.
+
+1. Update the `CHANGELOG.md` and `VERSION.txt` file by running the
+   [Prepare for Release](https://github.com/JLLeitschuh/ktlint-gradle/actions/workflows/prepare-release.yaml)
+   GitHub action.
+2. Verify that the [CHANGELOG.md](https://github.com/JLLeitschuh/ktlint-gradle/blob/master/CHANGELOG.md) file looks good.
+
+   **NOTE**: The `## [Unreleased]` header should still remain in the document, but should be empty.
+   This is expected by the GitHub release note upload step.
+3. Run the
+   [Perform Release](https://github.com/JLLeitschuh/ktlint-gradle/actions/workflows/perform-release.yaml) GitHub action.
+   This will actually perform the release.
