+# Contributing to obs-websocket
+
+## Translating obs-websocket to your language
+
+Localization happens on [Crowdin](https://crowdin.com/project/obs-websocket)
+
+## Branches
+
+**Development happens on `4.x-current`**
+
+## Writing code for obs-websocket
+
+### Code Formatting Guidelines
+
+* Function and variable names: snake_case for C names, camelCase for C++ method names
+
+* Request and Event names should use MixedCaps names
+
+* Request and Event json properties should use camelCase. For more detailed info on property naming, see [Google's JSON Style Guide](https://google.github.io/styleguide/jsoncstyleguide.xml)
+
+* Code is indented with Tabs. Assume they are 8 columns wide
+
+* 80 columns max code width. (Docs can be larger)
+
+* New and updated requests/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).
+
+### Code Best-Practices
+
+* 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();
+```
+
+* Some example common response/request property names are:
+    * `sceneName` - The name of a scene
+    * `sourceName` - The name of a source
+    * `fromScene` - From a scene - scene name
+
+### Commit Guidelines
+
+* Commits follow the 50/72 standard:
+    * 50 characters max for the commit title (excluding scope name)
+    * One empty line after the title
+    * Description wrapped to 72 columns max width per line.
+
+* Commit titles:
+    * Use present tense
+    * Prefix the title with a "scope" name
+        * e.g: "CI: fix wrong behaviour when packaging for OS X"
+        * Typical scopes: CI, General, Requests, Events, Server
+
+**Example commit:**
+
+```
+Requests: Add GetTransitionPosition
+
+Adds a new request called `GetTransitionPosition` which gets the current
+transition's state from 0.0f to 1.0f. Works with both auto and manual
+transitions.
+```
+
+### 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 newly named branch based on the upstream main one (e.g.: `feature/cool-new-feature`, `bugfix/fix-palakis-mistakes`, ...)
+
+* Only open a pull request if you are ready to show off your work.
+
+* If your work is not done yet, but for any reason you need to PR it (like collecting discussions, testing with CI, getting testers),
+    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").

+### Homebrew
+
+If you're using MacOS you can use Homebrew for installation as well:

 ## 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/
+
+Here is a list of available web clients: (compatible with tablets and other touch interfaces)
+
+- [Niek/obs-web](https://github.com/Niek/obs-web)
+- [t2t2/obs-tablet-remote](https://github.com/t2t2/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).

+### Securing obs-websocket (via TLS/SSL)
+
+If you are intending to use obs-websocket outside of a LAN environment, it is highly recommended to secure the connection using a tunneling service.
+
+See the SSL [tunnelling guide](SSL-TUNNELLING.md) for easy instructions on how to encrypt your websocket connection.

+# Connecting over a TLS/secure connection (or remotely)
+
+If you want to expose the WebSocket server of obs-websocket over a secure TLS connection (or to connect remotely), the easiest approach is to use a localhost tunneling service like [ngrok](https://ngrok.com/) or [pagekite](https://pagekite.net/).
+
+**Before doing this, secure the WebSocket server first by enabling authentication with a strong password!**
+
+**Please bear in mind that doing this will expose your OBS instance to the open Internet and the security risks it implies. *You've been warned!***
+
+
+## ngrok
+
+[Install the ngrok CLI tool](https://ngrok.com/download) on a linux OS, then start ngrok bound to port 4444 like this:
+
+```bash
+ngrok http 4444
+```
+
+The ngrok command will output something like this:
+
+```text
+ngrok by @inconshreveable
+
+Tunnel Status                 online
+Version                       2.0/2.0
+Web Interface                 http://127.0.0.1:4040
+Forwarding                    http://TUNNEL_ID.ngrok.io -> localhost:4444
+Forwarding                    https://TUNNEL_ID.ngrok.io -> localhost:4444
+```
+
+Where `TUNNEL_ID` is, as the name implies, the unique name of your ngrok tunnel. You'll get a new one every time you start ngrok.
+
+Then, use `wss://TUNNEL_ID.ngrok.io` to connect to obs-websocket over TLS.
+
+See the [ngrok documentation](https://ngrok.com/docs) for more tunneling options and settings.
+
+
+## PageKite
+
+[Install the PageKite CLI tool](http://pagekite.net/downloads), then start PageKite bound to port 4444 like this (replace NAME with one of your choosing):
+
+```bash
+python pagekite.py 4444 NAME.pagekite.me
+```
+
+Then, use `wss://NAME.pagekite.me` to connect to obs-websocket over TLS.
