-# Welcome to the GoldSource API docs
-
-This documentation is an attempt on explaining inner workings of Valve's Half-Life (R) engine, also known as GoldSource, from programmer's perspective. A deep knowledge of Quake (NQ, QW and Q2) engines is required.
-
-Everything discussed here is it's author assumption based on studying Xash3D source code and reverse engineering Half-Life mods. Xash3D API extensions is out of scope of this document and will be explained separately.

-# Initializing client.dll
-
-`client.dll` has got multiple ways of initialization during it's life but we will go through the simplest and the most common route here.
-
-Here we expect that reader has knowledge of loading dynamic shared objects on their platform. On Windows it's done through `LoadLibrary`/`GetProcAddress`/`FreeLibrary` functions, on POSIX-complaint systems it's done through `dlopen`/`dlsym`/`dlclose` functions.
-
-## client.dll lifetime
-
-`client.dll` is expected to be loaded during client initialization and unloaded on client shutdown. Essentially, in non-dedicated builds, it always exists during the engine lifetime. Judging by the API, it might look like `client.dll` might be safely unloaded and loaded again, for example for implementing classic `Change Game` functionality from WON versions of Half-Life, but in practice it's nearly impossible to do this clean in standard and portable manner. If you want to implement changing games, consider using `execv`-like functions.
-
-## client.dll exported functions
-
-The first thing you should do, is to acquire pointers to all exported functions, which you can find in the next chapter. Some of them are optional, and might not present in the `client.dll`, and will be labeled as such.
-
-## client.dll initialization process
-
-1. The first function you call is `Initialize` function, which lets `client.dll` to store a copy of an engine API functions.
-2. Since SDK 2.0, `client.dll` have player movement code in it, which you must initialize through `HUD_PlayerMoveInit` function. `client.dll` might want to override player hulls, which can be grabbed with `HUD_GetHullBounds` function.
-3. HUD functionality must be started up with `HUD_Init` function and can be de-initialized with `HUD_Shutdown` export function.
-4. And finally, SDK 2.1 brings studio model renderer, which has separate set of API functions, which must be initialized with `HUD_GetStudioModelInterface` function.

-
-### `void HUD_PlayerMoveInit( struct playermove_s *ppmove, int server )`
-
-> [!IMPORTANT]
-> This function is only called once.
-
-Called on player movement prediction initialization, before HUD. In GoldSrc, engine only runs prediction loop, the players physics are implemented in `client.dll`.

-
-> [!IMPORTANT]
-> This function is optional.
-
-Called to notify `client.dll` about an `svc_director` message. This feature is used for HLTV, though mods use it to spawn text messages or execute commands (bypassing `svc_stufftext` filter in old `client.dll`) but `svc_director` message structure isn't enforced by engine, so it in theory mods might modify it for their own needs.
-
-* `size` is the size of the payload

-* `talking` if true, this client is talking
-
-### `void HUD_ChatInputPosition( int *x, int *y )`
-
-> [!IMPORTANT]
-> This function is optional.

-# What is client.dll in GoldSource?
-
-One of technical differences a programmer working with Quake engine might notice is the client.dll file. Historically, it appeared somewhere in between Alpha 0.52 and NetTest1 development and judging by Half-Life SDK 1.0 was meant to handle HUD rendering. The time moved forward, SDK 2.0 finalized `client.dll` API at version 7, added an in-game UI, custom input processing, player movement and weapon prediction, very basic rendering through TriAPI. SDK 2.1 added ability to re-define studio model rendering, and so on.
-
-It somewhat resembles `cgame` module from Quake 3, but more crudely designed and sometimes feels like an afterthought, considering how many engine internal structures it exposes and the main point of incompatibilities with mods, which these days sometimes use `client.dll` as a way to inject custom rendering into the game.
-
-In this document I will try to go through each step, letting you, dear reader, implement your own GoldSrc compatible API in your Quake fork, targetting vanilla Half-Life `client.dll` from latest update, which at the time of writing, is 25-th anniversary update.
-
-Despite that we call it `client.dll`, since SDK 2.4 (unofficial naming, it's the first SDK Valve published on GitHub) it is considered portable and only has SDL2 and VGUI libraries in it's external dependences. It's only called this way to avoid possible misunderstandings with engine developers, who might interpret client as `cl_` prefixed part of Quake engine.

-# `client.dll` shared structs and enums
-
-GoldSource exposes a lot of structs to `client.dll`. Some of them are specific to `client.dll` and only used for passing data between engine and client, some of them are used in the engine everywhere, but still exposed in the public SDK. However, many mods rely on internal structs as well, and I will try to shed light on them as well.
-
-When implementing them in C, consider the default to 32-bit systems alignment of 4 bytes and ILP32 data type model.
-
-This file won't have API structs, for that, there should be separate chapters.

 As Xash3D accidentally supports GoldSrc games, it also supports parsing liblist.gam.\
 Xash3D will use this file if gameinfo.txt is absent, or if its modification timestamp is older than liblist.gam.
 
-> [!NOTE]
-> Starting from January 2025, Xash3D FWGS doesn't automatically generate gameinfo.txt from liblist.gam. The key conversion table still remains but if you wish to use gameinfo.txt instead of liblist.gam, you can execute `fs_make_gameinfo` in console.
-
 For game creators who plan supporting only Xash3D, using this file is not recommended.
 
 The table below defines conversion rules from liblist.gam to gameinfo.txt. Some keys' interpretation does differ from `gameinfo.txt`, in this case a note will be left. If `liblist.gam` key isn't present in this table, it's ignored.
