+OTHER CONTENT IN CDIST REPOSITORY
+---------------------------------
+Usually the cdist repository contains all configuration
+items. Sometimes you may have additional resources that
+you would like to store in your central configuration
+repositiory (like password files from KeepassX,
+Libreoffice diagrams, etc.).
+
+It is recommended to use a subfolder named "non-cdist"
+in the repository for such content: It allows you to
+easily distinguish what is used by cdist and what not
+and also to store all important files in one
+repository.
