+Eventor
+=======
+
+A simple tool to convert EuroPython's json files to an ICS file.
+
+Clone EuroPython's [website repo](https://github.com/EuroPython/website/).
+Then install and use this tool:
+
+```bash
+python3 -m venv venv
+source venv/bin/activate
+pip install ./eventor
+eventor -j '~/path/to/europython/website/src/content/days/*.json'
+```
+
+This will write a calendar.ics file in the current directory that you can then import to your favorite calendar app.
