This keeper will automatically liquidate unhealthy positions in the Mycelium Swaps contracts. It can either be run as a single container, connecting to an external MongoDB database, or the database and keeper can be run together with docker-compose.
To setup the environment, copy the env.example file to .env and set the variables.
