+# 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.
