 # Compiling obs-websocket
+
 ## Prerequisites
-You'll need [QT 5.9.0](https://download.qt.io/official_releases/qt/5.7/5.7.0/), CMake, and a working development environment for OBS Studio installed on your computer. 
+
+You'll need [Qt 5.10.x](https://download.qt.io/official_releases/qt/5.10/),
+[CMake](https://cmake.org/download/) and a working [OBS Studio development environment](https://obsproject.com/wiki/install-instructions) installed on your
+computer.
 
 ## Windows
+
 In cmake-gui, you'll have to set the following variables :
+
 - **QTDIR** (path) : location of the Qt environment suited for your compiler and architecture
 - **LIBOBS_INCLUDE_DIR** (path) : location of the libobs subfolder in the source code of OBS Studio
 - **LIBOBS_LIB** (filepath) : location of the obs.lib file
 - **OBS_FRONTEND_LIB** (filepath) : location of the obs-frontend-api.lib file
 
 ## Linux
+
 On Debian/Ubuntu :
-```
-sudo apt-get install libqt5websockets5-dev
+
+```shell
+sudo apt-get install libboost-all-dev
 git clone --recursive https://github.com/Palakis/obs-websocket.git
 cd obs-websocket

 ## OS X
-Use of the Travis macOS CI scripts is recommended. Please note that these scripts install new software and can change several settings on your system. An existing obs-studio development environment is not required, as `install-dependencies-macos.sh` will install it for you.
-Of course, you're encouraged to dig through the contents of these scripts to look for issues or specificities.
-```
+
+As a prerequisite, you will need Xcode for your current OSX version, the Xcode command line tools, and [Homebrew](https://brew.sh/).
+Homebrew's setup will guide you in getting your system set up, you should be good to go once Homebrew is successfully up and running.

+Use of the Travis macOS CI scripts is recommended. Please note that these
+scripts install new software and can change several settings on your system. An
+existing obs-studio development environment is not required, as

+working obs-studio development environment and have built obs-studio, you can
+skip that script.

+Of course, you're encouraged to dig through the contents of these scripts to
+look for issues or specificities.

 cd obs-websocket
 ./CI/install-dependencies-macos.sh
+./CI/install-build-obs-macos.sh
 ./CI/build-macos.sh
 ./CI/package-macos.sh
 ```
+
 This will result in a ready-to-use `obs-websocket.pkg` installer in the `release` subfolder.

 ## Downloads
+
 Binaries for Windows and Linux are available in the [Releases](https://github.com/Palakis/obs-websocket/releases) section.
 
 ## 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)
 - 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
+
+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
+
+**New features and fixes must be based off and contributed to `4.x-current`**, as obs-websocket 5.0 is not in active development yet.
+
+### Pull Requests
+
+Pull Requests must never be based off your fork's main branch (in our case, `4.x-current` or `5.x`). 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, 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.
+
+### 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();
+```
+

 # General Introduction
 Messages are exchanged between the client and the server as JSON objects.
 This protocol is based on the original OBS Remote protocol created by Bill Hamilton, with new commands specific to OBS Studio.

 # Authentication
-OBSWebSocket uses SHA256 to transmit credentials.
+`obs-websocket` uses SHA256 to transmit credentials.
 
 A request for [`GetAuthRequired`](#getauthrequired) returns two elements:
 - A `challenge`: a random string that will be used to generate the auth response.
