 **This variable has no effect if nexus_version is fixed in your vars**
 
-Unless you set this variable, the role will keep the current installed nexus version when running against an already provisionned host. Passing this extra var will trigger automatic latest nexus version detection and upgrade if a newer version is available.

 We strongly suggest to use this variable only as an extra var to ansible-playbook call
 ```bash
 ansible-playbook -i your/inventory.ini your_playbook.yml -e nexus_upgrade=true
 ```
 
+#### Skip provisionning tasks
+```yaml
+    nexus_run_provisionning: false
+```
+This var is unset by default and will default to `true`. Setting it to `false` will cause the role to skip all of the
+provisionning tasks and will therefore *not create/update*:
+* ldap configurations
+* content selectors
+* privileges
+* roles
+* users (except checking/updating admin password)
+* blobstores
+* repositories
+* tasks (backup will still be configured if enabled)
+
+This can save time if you have lots of configured repositories/users/roles... and you want to play the role
+to simply check nexus is correctly installed, or restore a backup, or upgrade nexus version.

+We strongly suggest to use this variable only as an extra var to ansible-playbook call
