+
+## Release
+
+To create a new release make a PR from `develop` into `main`. Once this is merged if the version number has changed a signed build will then be created and pushed to maven central. If all checks pass this will go live automatically (This may take up to 48 hours).
+
+Once this is complete create a mergeback from `main` into `develop` to keep both branches in sync.
