 # Provisioning from the target platform itself
 It is possible to run playbooks directly on the target platform.
+In this case, you have to always pass `ansible_user=pmdkuser` as an additional

+the `ansible_user` variable is defined. When running on a remote target the
+connection plugin does it for you.

 To run playbooks inside the platform please comment out the line:
