 ## Usage:
 `thingy_grabber.py user_name collection_name`
+
 Where `user_name` is the name of the creator of the collection (not nes. your name!) and `collection_name` is the name of the collection you want.
 
+This will create a series of directorys `user-collection/thing-name` for each thing in the collection.
+If a thing's directory already exists, it will be skipped.
+
+If for some reason a download fails, it will get moved sideways to `thing-name-failed` - this way if you rerun it, it will only reattmpt any failed things.
