 ## Description
 
-This module is exporting a structured fact hash ("packages") which contains all installed (RPM-) packages and their versions.  
-This includes packages which are installed as a dependency and not managed via Puppet directly.
+This module is exporting a structured fact hash ("packages") which contains all installed (RPM-) packages and their versions (including release and architecture).  
+It includes packages which are installed as a dependency and not managed via Puppet directly.
+As packages can be installed multiple times with different versions (e.g. "kernel"), the output is always an array with all installed versions.
 
 It is intended to be used together with PuppetDB to provide a fast and reliable way to query all packages and versions in your infrastructure.
