+A single category for the application to be placed in. There is no fixed list
+of categories - both the client and the web site will automatically show any
+categories that exist in any applications. However, if your metadata is
+intended for the main F-Droid repository, you should probably use one of the
+existing categories (look at the site/client), or discuss the proposal to add
+a new one.
