 ## Playbook versioning
 
-Every time you edit a playbook, a new version of the playbook is saved. In the screen image below, notice how all the versions of the playbook are listed (#4 being the published version as indicated by the publish icon). Click on a version to edit it, and if you want, publish it. In this way, you maintain version control of your playbooks, and ensure that all versions are retained.

+
+When the automatic save is complete, the following notification lets you know.<br/><img src={useBaseUrl('img/platform-services/automation-service/autosave-playbook-2.png')} alt="Playbook autosave complete" style={{border:'1px solid gray'}} width="200"/>
