 ## 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, ...)
 
 ### For developers
+
 The server is a typical Websockets server running by default on port 4444 (the port number can be changed in the Settings dialog).
 The protocol understood by the server is documented in [PROTOCOL.md](docs/generated/protocol.md).

 ## Compiling obs-websocket
+
 See the [build instructions](BUILDING.md).
 
+## Contributing
+
+### Branches
+
+Development happens on `4.x-current`
+
+### Pull Requests
+
+Pull Requests must never be based off your fork's main branch (in this case, `4.x-current`). Start your work in a new branch
+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, 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 required to automatically generate the [protocol specification document](docs/generated/protocol.md).
+
+Among other recommendations: favor return-early code and avoid wrapping huge portions of code in conditionals. As an example, this:
+
+```cpp
+if (success) {
+    return req->SendOKResponse();
+} else {
+    return req->SendErrorResponse("something went wrong");
+}
+```
+
+is better like this:
+
+```cpp
+if (!success) {
+    return req->SendErrorResponse("something went wrong");
+}
+return req->SendOKResponse();
+```
+
