+#### Default Root Folders
+
+When setting up Sonarr/Radarr in Ombi, the option to "Load Folders" allows you to define what 'root folder' requested content should be put into by the relevant *arr.  
+If you are using 'atomic' mapping (i.e. direct media location in a containerised *arr), you will still need to define a root folder in it in order for you to be able to use Ombi.  
+_Note, in some older versions of Sonarr this was not an issue as it would supply a default location if the API was queried, but this behaviour seems to have been removed._
