 You should replace `TELEGRAM_BOT_TOKEN` and `TELEGRAM_BOT_USERNAME` at least before starting.  
 Start is simple as `docker-compose up --build -d`  
 
-**Note:** Docker has very annoing [bug #2259](https://github.com/moby/moby/issues/2259) that will cause exception on first start:  
-```Unable to create file /var/log/spodlivoi.log java.io.IOException: Permission denied```   
-If you encountered this, run once on your host: 
-```chown -R $(docker-compose exec spodlivoi id -u) $(docker inspect spodlivoibot_spodlivoilogs -f {{.Mountpoint}})```  
-Although, if you don't need persistent logs, you can simply ignore this.
