 Sets the rich presence object for the currently logged in user. Rich presence is Valve's solution to giving friends information on what you're doing in a game. For example, when you see information about another friends matchmaking game (as in, the map and score), this is set by using rich presence. An example of how to use this method can be found in [example.js](https://github.com/joshuaferrara/node-csgo/blob/master/example/example.js)
 
+## Item Data
+
+### `itemDataRequest(string s, string a, string d, string m)`
+
+Requests item data for the specified CSGO item inspect link parameters. The parameter `s` has a value when the inspect link is from an inventory; likewise, the parameter `m` has a value when the inspect link is from the market. If there is no value for a given parameter from the inspect link, set it to `"0"`. 
+
+Listen for the `itemData` event for the game coordinator's response.

 ### `unready`
 Emitted when the connection status to the GC changes, and renders the library unavailable to interact.  You should clear any event handlers set in the `ready` event here, otherwise you'll have multiple handlers for each message every time a new `ready` event is sent.
