+## Docker
+The docker image is not yet fully usage. The intention is to have a `le-easy-certs` container 
+running next to a a `haproxy` container and automatically renew / update the certificates when 
+needed. Also the certificates could be hot reloaded in `haproxy` at some point.
+
+Right now the docker image could be used to run `le-easy-certs` manually / automated at fixed times 
+controlled by the host.
