 Example Playbook
 ----------------
 
+Default behavior:
+
+```yaml
+---
+- name: Check cert expirys
+  hosts: all
+  become: yes
+  gather_facts: no
+  roles:
+    - role: openshift_certificate_expiry
+```
+
+Generate HTML and JSON artifacts in their default paths:
+
+```yaml
+---
+- name: Check cert expirys
+  hosts: all
+  become: yes
+  gather_facts: no
+  vars:
+    generate_html_report: yes
+    save_json_results: yes
+  roles:
+    - role: openshift_certificate_expiry
 ```
+
+Change the expiration warning window to 1500 days (good for testing
+the module out)
+
+```yaml
+---
 - name: Check cert expirys
   hosts: all
   become: yes
   gather_facts: no
+  vars:
+    warning_days: 1500
   roles:
