+A simple API for episodes of My Little Pony: Friendship is Magic to be run
 inside a container.
+
+API Usage
+---------
+
+An episode will have the following data type:
+
+```json
+{
+      "air_date": 1286735400,
+      "episode": 1,
+      "is_movie": false,
+      "name": "Friendship is Magic Part 1",
+      "season": 1
+}
+```
+
+This represents Season 1, Episode 1 of My Little Pony: Friendship Is Magic. The
+`air_date` column represents the date and time that the episode was originally
+shown on The Hub (now Discovery Family Network). If `is_movie` is set and the
+season number is `99`, the episode record should be treated as a movie.
+
+### `/all`
+
+Returns all information about all episodes. This returns an array of Episode
+objects as defined above.
+
+### `/season/<number>`
+
+Returns all information about episodes in the given season number or a `404`
+reply if no episodes could be found. To get all information about the movies
+shown, set the season as `99`.
+
+### `/season/<number>/episode/<number`
+
+Returns all information about the episode with the given season and episode
+number. If the episode cannot be found, this will return a `404`.
+
+### `/random`
+
+Returns a random episode record from the list of episodes.
+
+### `/search`
+
+This must be given a query paramater `q` containing the text to search for. Not
+including this will return a `406` reply. This will search the list of episode
+records for any episodes whose names match the given search terms. This is
+case-insensitive. If no episodes can be found, this will return a `404` reply.
