+###### Retrieving objects
+
+The HTTP GET method may be dereferenced against an object's `id` property to retrieve the activity.
+The plugin supports HTTP content negotiation as defined in [RFC7231](https://tools.ietf.org/html/rfc7231) in every endpoint suffixed with .json .
+The plugin always presents ActivityStreams object representation in response to every request.
+The client MUST specify an `Accept` header with the `application/ld+json; profile="https://www.w3.org/ns/activitystreams"` media type in order to retrieve the activity.
+
 ###### Selecting ranges
 
 For most `GET` operations that return arrays, the query parameters `max_id` and `since_id` can be used to specify the range of IDs to return.
