 # Webframe
 
+![WebFrame](example.jpg)
+
 A simple digital picture frame as a website.
 
-Inspired by TeleFrame https://github.com/LukeSkywalker92/TeleFrame
+With webframe you can turn any device with a screen and browser into a digital picture frame.
+
+To minimize friction (sync, multi user support) the images are downloaded from a webdav share (e.g. [nextcloud](https://nextcloud.com/)).
+
+This project is heavily inspired by [TeleFrame](https://github.com/LukeSkywalker92/TeleFrame).
