 ## Runtime Dependencies
 * A Bot has to be created using [@BotFather](https://t.me/BotFather), which produces a Token
+* An instance of (Mensa-API)[https://github.com/greybaron/mensa-api] has to be running. The API url must be passed, for example `API_URL=http://url:9090`. Can be set by env variable or launch argument, run this program with option `-h` for details. ℹ️ There is a branch "standalone" which doesn't need this API, however it won't receive further updates.
 * If using the CampusDual feature, the `GEANT OV RSA CA 4` certificate must be installed. On most Linux distributions, this certificate is not shipped
 * Any data that is persisted is saved to SQLite3 databases in the current working directory, so it should be ensured that the directory is writable and not volatile
