+## Maintenance
+
+### CI
+This project uses the [sbt-ci-release](https://github.com/sbt/sbt-ci-release) for generating GitHub actions in the `.github` actions directory, based on declared build configuration in `github-actions.sbt`. 
+
+When making changes to `github-actions.sbt` job declarations, the Github actions should be updated to reflect these changes by running the following task:
+
+```
+sbt githubWorkflowGenerate
+```
+
+### Releasing
+
+To release a new version of this plugin simply create a new tag against the intended release commit which should trigger the `release` Gitbhub action.
