-# Release
+# Automated release procedure
+
+A make script has been created to automate the manual procedure.
+Execute the following command:
+```bash
+make gh-release NEW_VERSION=v0.6.0 OLD_VERSION=v0.5.0 DESCRIPTION="A test release to see how it works"
+```
+
+`NEW_VERSION` is the version that you want to release.
+`OLD_VERSION` is the previous version you wish to overwrite in the markdown and yaml files.
+`DESCRIPTION` is the description to use in the annotation of the tag and commit description.
+
+# Manual release procedure
 
 1. Upgrade version number in all repository files, find & replace previous version number with new version number.
 1. Commit the changed files.
 1. Tag the new commit using `git tag -sam "What is this release about?" v0.1.0`.
-
-## Experimental
-
 1. Push the tag to remote using `git push v0.1.0`
 1. Wait for the release workflow to finish, then push the main branch using `git push`
