 ## Using obs-websocket
+
 A web client and frontend made by [t2t2](https://github.com/t2t2/obs-tablet-remote) (compatible with tablets and other touch interfaces) is available here : http://t2t2.github.io/obs-tablet-remote/
 
 It is **highly recommended** to protect obs-websocket with a password against unauthorized control. To do this, open the "Websocket server settings" dialog under OBS' "Tools" menu. In the settings dialogs, you can enable or disable authentication and set a password for it.
 
 ### Possible use cases
+
 - Remote control OBS from a phone or tablet on the same local network
-- Change your stream overlay/graphics based on the current scene (like the AGDQ overlay does)
+- Change your stream overlay/graphics based on the current scene
 - Automate scene switching with a third-party program (e.g. : auto-pilot, foot pedal, ...)

 ### Branches
 
-The two main development branches are:
-
-- `4.x-current`: actively-maintained codebase for 4.x releases. Backwards-compatible (unless stated otherwise) with existing clients until 5.0.
-- `5.x`: upcoming 5.0 version
-

 based on the main one (e.g.: `cool-new-feature`, `fix-palakis-mistakes`, ...) and open a Pull Request once you feel ready to show your work.
 
-If your Pull Request is not ready to merge yet, tag it with the `work in progress` label. You can also use the `help needed` label if you have questions, need a hand or want to ask for input.
+**If your Pull Request is not ready to merge yet, create it as a Draft Pull Request** (open the little arrow menu next to the "Create pull request" button, then select "Create draft pull request").
 
 ### Code style & formatting
 
 Source code is indented with tabs, with spaces allowed for alignment.
 
 Regarding protocol changes: new and updated request types / events must always come with accompanying documentation comments (see existing protocol elements for examples).
-These are using to automatically generate the [protocol specification](docs/generated/protocol.md).
