+# Tools/config for University of Tübingen
+
+## Config
+
+-   eduroam for iwd: Move `eduroam.8021x` to `/var/lib/iwd/`. Move the
+    public certificate `eduroam.crt` to `/opt/eduroam.crt`. Don't forget
+    to assign the correct permissions.
+
+## Scripts
+
+-   `almanot`: Get notifications if something on Alma changes. Uses the
+    official RSS feed endpoint.
+-   `iliasnot`: Get notifications for changes of course pages.
+    *UNOFFICIAL* scraping method, only use this script if you have
+    permission to scrape the website!
+
+Then `crontab -e` and `*/10 * * * * <PATH>/almanot` to check every 10
+minutes.
