+# Releasing Patch Shorebird
+
+These are the steps needed to create a new release:
+
+1. Create a new release in GitHub
+   - Click on `Releases -> Draft a new release`
+1. Make sure to name the release `v<VERSION>` (e.g. v1.2.3)
+1. Click on `Generate release notes`
+1. Click on `Publish release`
+1. Update the current major version tag to point to the latest release. For example, if we just released v0.1.2, we'll need to make sure the `v0` tag points to the same commit as `v0.1.2`
+   ```sh
+   # force update the latest release tag
+   git tag -f v0 v0.1.2
+   # push the tag
+   git push origin :refs/tags/v0
+   ```
