+## Automation
+
+Two scripts are currently in place to:
+
+- [update-readme.py](./update-readme.py) - updates the README.md file with the data from the releases.json file
+- [ical.py](./ical.py) - generates an iCal file from the releases.json file
+
 ## Roadmap
 
   - [ ] Double check dates and make the repo public
