 # Running `just` commands
 
 We have previously used [make](https://www.gnu.org/software/make/) for easily running some playbook commands (e.g. `make roles` which triggers [`ansible-galaxy`](https://docs.ansible.com/ansible/latest/cli/ansible-galaxy.html)). Our [`Makefile`](../Makefile) is still around, and you can still run these commands.
