+## Discord Game SDK
+
+> The SDK is currently under extensive development and is subject to change. Suggestions
+> about the current API are welcome.
+
+### Setup
+
+- Create an application on the Discord [developer site](https://discordapp.com/developers/applications/me).
+- Set a redirect URL. If you don't have one right now, just use <http://127.0.0.1>.
+- Enable Rich Presence for the application. This enables whitelist access for the SDK.
+  - When you are ready to test with more people, add them to the whitelist.
+- Copy the **Client ID**.
+  - Use this `CLIENT_ID` when initializing the SDK.
