 - `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 `@`).

 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.

 ## 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`
@@ -31,13 +34,14 @@ obs-websocket provides a feature-rich RPC communication protocol, giving access

 - 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`.

 ### 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):

 ## Message Types (OpCodes)
+
 The following message types are the low-level message types which may be sent to and from obs-websocket.
