+
+Tvheadend supports multiple different fanart grabbers/providers, and
+can be extended with third-party grabbers.
+
+Grabbers frequently require additional options such as "api keys",
+which are generated by registering at the appropriate site.
+
+If you do not register and provide the api keys then the
+fanart grabber will fail.
+
+Modules that are supplied with Tvheadend are listed below.
+
+Module | Extra Arguments                | Description
+:-----:|--------------------------------|------------
+tmdb   | `--tmdb-key ABC`               | Key from [tmdb.org](https://www.themoviedb.org/account/signup) (Movies)
+tvdb   | `--tvdb-key ABC`               | Key from [thetvdb.com](https://www.thetvdb.com/login) (TV Series)
+tvdb   | `--tvdb-languages en,sv,hu,de` | Languages to use for searching for episode.
+
+Fanart grabbers only work correctly if your scrapper provides
+high quality information. In particular, they require season
+and episode details for series, and year details for movies.
+
+Even with these details, fanart grabbers can sometimes return
+incorrect results.
+
+Optional extra arguments can be supplied to alter behaviour.
+Notable arguments are below:
+
+Argument          | Description
+:----------------:| -------------
+`--debug`         | Provide extra level of debugging information
+`--modules-tv`    | Advanced option specifying a csv of tv modules to use.
+`--modules-movie` | Advanced option specifying a csv of movie modules to use.
