 To do so, we must tell ansible which servers compose our infrastructure. This is done thanks to an `inventory` file.
 The default `inventory` file for ansible is located in `/etc/ansible/hosts`.
 
+For now, your inventory is empty, so you can create one:
+
 ```
-cat /etc/ansible/hosts
+mkdir -p /etc/ansible/
+touch /etc/ansible/hosts
 ```
 
-It's empty by default (not really empty, but everything is commented).
 With an empty `inventory` like that, ansible only knows about `localhost`.
