 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:
+First, make sure all settings within `defaults/main.yml` are correct for your
+server. All settings and their purposes are outline in the section above.
 
-    - hosts: servers
-      roles:
-         - { role: username.rolename, x: 42 }
+Create a new ansible play. You can name it whatever you want, but this
+example play will simply be named `fail2ban.yml`.
+
+```yml
+---
+- hosts: testserver
+  become: yes
+  roles:
+  - fail2ban
+```
+
+Make sure the IP for `testserver` is correct in the `/etc/ansible/hosts` file -
+```
+[testserver]
+123.123.123.123:22
+```
+
+Run the play!
+
+```bash
+ansible-playbook fail2ban.yml
+```
