 ## Deployment
 
 The bot can be run either using [cargo](https://doc.rust-lang.org/cargo/), or the provided Docker image.
 
 The latter is preferred, since it allows off-the-shelf use. The configuration required is the same as specified above, the config file can directly be mounted in the container.
