+## Academic profile
+
+The footer on the home screen has a **Configure UniOS** button. It opens a page where you pick your university and department from dropdowns, which is saved to `~/.unios/academicConfig.json`. Other UniOS apps (such as UniBackpack) read this file, so the available choices live in `academic_institutions.py` and must stay in sync with those apps. If UniBackpack adds new universities or departments, mirror them in `academic_institutions.py`.

 ## Contributing
 
 Contributions are welcome. If you want to improve the UI, fix a typo, or add a new page, open a pull request on GitHub. If you find a bug, open an issue. There is no contribution too small.
