-# obs-websocket documentation
-
-This is the documentation for obs-websocket. Run build_docs.sh to auto generate the latest docs from the `src` directory. There are 3 components to the docs generation:
-- `comments/comments.js`: Generates the `work/comments.json` file from the code comments in the src directory.
-- `docs/process_comments.py`: Processes `work/comments.json` to create `generated/protocol.json`, which is a machine-readable documentation format that can be used to create obs-websocket client libraries.
-- `docs/generate_md.py`: Processes `generated/protocol.json` to create `generated/protocol.md`, which is the actual human-readable documentation.
-
-Some notes about documenting:
-- The `complexity` comment line is a suggestion to the user about how much knowledge about OBS's inner workings is required to safely use the associated feature. `1` for easy, `5` for megadeath-expert.
-- The `rpcVersion` comment line is used to specify the latest available version that the feature is available in. If a feature is deprecated, then the placeholder value of `-1` should be replaced with the last RPC version that the feature will be available in. Manually specifying an RPC version automatically adds the `Deprecated` line to the entry in `generated/protocol.md`.
-- The description can be multiple lines, but must be contained above the first documentation property (the lines starting with `@`).
-- Value types are in reference to JSON values. The only ones you should use are `Any`, `String`, `Boolean`, `Number`, `Array`, `Object`.
-  - `Array` types follow this format: `Array<subtype>`, for example `Array<String>` to specify an array of strings.
-
-Formatting notes:
-- Fields should have their columns aligned. So in a request, the columns of all `@requestField`s should be aligned.
-- We suggest looking at how other enums/events/requests have been documented before documenting one of your own, to get a general feel of how things have been formatted.

-Example code comment:
-```
-/**
-* The initial message sent by obs-websocket to newly connected clients.
-*
-* @enumIdentifier Hello
-* @enumValue 0
-* @enumType WebSocketOpCode
-* @rpcVersion -1

 ## General Intro
+
 obs-websocket provides a feature-rich RPC communication protocol, giving access to much of OBS's feature set. This document contains everything you should know in order to make a connection and use obs-websocket's functionality to the fullest.
 
 ### Design Goals
+
 - Abstraction of identification, events, requests, and batch requests into dedicated message types
 - Conformity of request naming using similar terms like `Get`, `Set`, `Get[x]List`, `Start[x]`, `Toggle[x]`
 - Conformity of OBS data field names like `sourceName`, `sourceKind`, `sourceType`, `sceneName`, `sceneItemName`

 - PubSub system - Allow clients to specify which events they do or don't want to receive from OBS
 - RPC versioning - Client and server negotiate the latest version of the obs-websocket protocol to communicate with.

 - At any time after a client has been identified, it may send an [OpCode 3 `Reidentify`](#reidentify-opcode-3) message to update certain allowed session parameters. The server will respond in the same way it does during initial identification.
 
 #### Connection Notes
+
 - If a binary frame is received when using the `obswebsocket.json` (default) subprotocol, or a text frame is received while using the `obswebsocket.msgpack` subprotocol, the connection is closed with `WebSocketCloseCode::MessageDecodeError`.
 - The obs-websocket server listens for any messages containing a `request-type` field in the first level JSON from unidentified clients. If a message matches, the connection is closed with `WebSocketCloseCode::UnsupportedRpcVersion` and a warning is logged.
 - If a message with a `messageType` is not recognized to the obs-websocket server, the connection is closed with `WebSocketCloseCode::UnknownOpCode`.

 ### Creating an authentication string
+
 obs-websocket uses SHA256 to transmit authentication credentials. The server starts by sending an object in the `authentication` field of its `Hello` message data. The client processes the authentication challenge and responds via the `authentication` string in the `Identify` message data.
 
 For this guide, we'll be using `supersecretpassword` as the password.
 
 The `authentication` object in `Hello` looks like this (example):
+
 ```json
 {
     "challenge": "+IxH4CnCiqpX1rM9scsNynZzbOe4KhDeYcTNS3PDaeY=",

 To generate the authentication string, follow these steps:

 - Generate an SHA256 binary hash of the result and base64 encode it, known as a base64 secret.
