+## Example Playbook
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:
+
+```yaml
+- hosts: all
+  roles:
+    - role: radiorabe.common.local-system-user
+      vars:
+        username: local-sys
+    - role: radiorabe.common.local-system-user
+      vars:
+        username: virtualizer
+        home_directory: /var/lib/libvvirt/images/
+        usergroups: 'libvirt,qemu'
+```
