 +Ansible is made to run all playbooks using this "playbooks" dir as your working directory. From there all relative paths works as intended.
 +
 +You can use some pre-defined playbooks using the Galaxy store :
 +
 +<code>
 +# List installed roles :
 +ansible-galaxy collection list
 +
 +# Installs a role from prometheus space called prometheus too :
 +ansible-galaxy collection install prometheus.prometheus
 +</code>
 +
 +You can run playbooks simply like this :
 +
 +<code>
 +ansible-playbook -i labs.ini calypso-sys.yml
 +</code>
 +
 +Or with more options :
 +
 +<code>
 +# Run only on calypso0 and calypso1, import the users.yml variable file to have all users UID/GID, start the playbook at the step that runs the ISC2 task
 +ansible-playbook -i labs.ini calypso-sys.yml --limit calypso0,calypso1 --extra-vars='@users.yml' --start-at-task="Check or Add ISC2 users"
 +</code>
