 By default, the bot expects its configuration file under `./config/config.yaml` next to the bot executable. Inside the Docker image the
 corresponding full path is `/home/bot/config/config.yaml`. If you prefer using a different location or even a different filename, you can
 also define the environment variable `GITEA_SQ_BOT_CONFIG_PATH` that allows for changing that full path.

+If there are port mapping issues, you can use any other free port from your host. If you wish to use another port for the bot itself, you can override the default port `3000` by using the environment variable `GITEA_SQ_BOT_PORT`. Let's say you want to consistently use port _9001_ inside and outside the container, a correct command would be:
