 ## Setup
 ### Ubuntu und Debian
-Falls du Ubuntu oder Debian verwendest, kannst du einfach `./install dependencies.sh` ausführen, damit alles installiert wird. Ergänze dann noch den `bot_api_key` und die `admin`-ID (Bekommst du in Telegram mit `@Brawlbot id`) und kopiere die config.lua.example nach config.lua.

 Für eine manuelle Installation musst du LuaRocks für 5.2 [selbst kompilieren](http://stackoverflow.com/a/20359102).
