 ### Backend
 
-The backend app is a Flask app, with entry point in `/var/www/pioreactorui/main.fcgi`. The app uses Huey as background workers to perform `pio` tasks, save to disk, etc. Huey is controlled by systemd `huey.service`. The API is [available here](/developer-guide/web-ui-api)

 ### Frontend
 
-The frontend is a React app, built with Material UI. The source code is at [pioreactorui_frontend](https://github.com/Pioreactor/pioreactorui_frontend). A lot of the "data" for the frontend comes from YAML files on the RPi's filesystem. For example, all the charts, activities, and automations are defined in their own YAML file in a `contrib` folder on the filesystem. This way, it's easy to add new data to the frontend without having to write new JS.
