+### Creating a new Release
+#### Composition Function
+Run the [CI action](https://github.com/crossplane-contrib/function-pkl/actions/workflows/ci.yml) and provide a Package version.
+#### Pkl Packages
+Update `PklProject.package.version` of the relevant Package in ./pkl/
+
+Create a Tag in the style of <PklProject.package.name>@<PklProject.package.version> e.g. `git tag [email protected]`
+
+Push it `git push --tags`
+
