+#### Docker
+
+In order to run `smolgit` in docker there is the [`Dockerfile`](/Dockerfile).
+
+1. Build image `make build-docker`
+1. Generate `config.yaml` file `make config-docker`, it'll create `config.yaml` in the current directory and mount it for docker.
+1. Run `smolgit` in docker:
+
+```shell
+$> make run-docker
+docker run -it -p 3080:3080 -p 3081:3081 -v /path-to-smolgit-project/smolgit/:/etc/smolgit smolgit
