+## "Build" it Yourself
+You can create the release ZIP file yourself by simply executing the `release.sh` script (Linux only, needs `sed` and `zip` (default on most distros)):
+```
+utils/release.sh
+```
+This script will automatically cut out all unnecessary comments and create a ZIP file. The content can be placed directly into the mod folder of Logic World. 
+> :warning: The version number is taken from the latest git tag.
 
 ## Acknowledgements
 Huge thanks to Mouse Hat Games (especially Jimmy) for the great game and the modularity making it super easy to create custom themes and other mods!
