+### Requests
+
+Method names for requests match the API calls but snake cased.
+
+example:
+
+```python
+cl = ReqClient()
+
+# GetVersion
+resp = cl.get_version()
+
+# SetCurrentProgramScene
+cl.set_current_program_scene()
+```
+
+For a full list of requests refer to [Requests](https://github.com/obsproject/obs-websocket/blob/master/docs/generated/protocol.md#requests)
+
+### Events
+
+When registering a function callback use the name of the expected API event in snake case form.
+
+example:
+
+```python
+cl = EventClient()
+
+def scene_created(data):
+    ...
+
+# SceneCreated
+cl.callback.register(scene_created)
+
+def input_mute_state_changed(data):
+    ...
+
+# InputMuteStateChanged
+cl.callback.register(input_mute_state_changed)
+
+# returns a list of currently registered events
+print(cl.callback.get())
+```
+
+cl.callback accepts both a single or list of functions.
+
+For a full list of events refer to [Events](https://github.com/obsproject/obs-websocket/blob/master/docs/generated/protocol.md#events)
+
+### Attributes
+
+For both request responses and event data you may inspect the available attributes using `attrs()`.
+
+example:
+
+```python
+resp = cl.get_version()
+print(resp.attrs())
+
+def scene_created(data):
+    print(data.attrs())
+```
+
+### Errors
+
+If a request fails an `OBSSDKError` will be raised with a status code.
+
+For a full list of status codes refer to [Codes](https://github.com/obsproject/obs-websocket/blob/master/docs/generated/protocol.md#requeststatus)
+
+### Tests
+
+First install development dependencies:
+
+`pip install -e .['dev']`
+
+To run all tests:
+
+```
+pytest -v
+```
