 ## Install
 
-You can download the app [here (German page)](http://www.ulisses-ebooks.de/product/209711) or here [here (English page)](http://www.drivethrurpg.com/product/220253) (same app on both pages). You'll get an installer for Windows with Auto Update support and a DMG for Mac. For Linux, you get an AppImage, which *should* support Auto Update but it doesnt seem to work currently. You also get a tar.gz if you don't like AppImage.
