+List of all avainble tags is [here](https://hub.docker.com/r/evilfreelancer/docker-routeros/tags/),
+`latest` will be used by default.

+```
+
+### Use image from docker hub
+
+```bash

+docker run -d -p 22:22 -p 8728:8728 -p 8729:8729 -ti evilfreelancer/docker-routeros
+```
+
+### Use in docker-compose.yml
+
+```yml
+version: "2"
+
