-In this mode, we emulate the behaviour of selected functions that may help running mods relying on engine bugs, but enabling them by default may break majority of other games.
 
 At this time, we only have implemented GoldSrc bug-compatibility. It can be enabled with `-bugcomp` command line switch.
 
+When `-bugcomp` is specified without argument, it enables everything. This behavior might be changed or removed in future versions.
+
+When `-bugcomp` is specified with argument, it interpreted as flags separated with `+`. This way it's possible to combine multiple levels of bug-compatibility.

+| ------- | ----------- | ---------------------------- |
-* `pfnPEntityOfEntIndex` in GoldSrc returns NULL for last player due to incorrect player index comparison
+| `peoei` | Reverts `pfnPEntityOfEntIndex` behavior to GoldSrc, where it returns NULL for last player due to incorrect player index comparison | * Counter-Strike: Condition Zero - Deleted Scenes |

+| `gsmrf` | Rewrites message at the moment when Game DLL attempts to write an internal engine message, usually specific to GoldSrc protocol.<br>Right now only supports `svc_spawnstaticsound`, more messages added by request. | * MetaMod/AMXModX based mods |
-### Games and mods that require this
+| `sp_attn_none` | Makes sounds with attenuation zero spatialized, i.e. have a stereo effect. | Possibly, every game that was made for GoldSrc. |
-
+| `get_game_dir_full` | Makes server return full path in server's `pfnGetGameDir` API function | Mods targetting engine before HL 1.1.1.1, according to MetaMod [documentation](http://metamod.org/engine_notes.html#GetGameDir) |

-```
-
-Use weapon_c4 after creating it.
-
-Note that you cannot use many dfferent callbacks at the same time.
-
-You can set entity name by by pattern and create special script, contatning all callbacks.
-
-Example:

-```
-if $ent_last_name == my_ent1_$name
-:(ent1 actions)
-if $ent_last_name == my_ent2_$name
-:(ent2 actions)
-```
-Note that scripting cannot be blocking. You cannot wait for server answer and continue. But you can use small scripts, connected with ent_last_cb command. The best usage is user interaction. You can add touch buttons to screen or call user command menu actions by callbacks.
-##  Server side
-
-To enable entity tools on server, set sv_enttools_enable to 1
-
-To change maximum number of entities, touched by ent_fire, change sv_enttools_maxfire to required number.
-
-To enable actions on players, set sv_enttools_players to 1.
-
-To enable entity tools for player by nickname, set sv_enttools_godplayer to nickname. Useful to temporary enable from rcon.

-To prevent crash on some actions, set host_mapdesign_fatal to 0

 ## Note on GoldSrc liblist.gam support
 
 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.

+# Support for GoldSrc network protocol
+This feature is still work-in-progress, but for now it's available for all users, and we appreciate any bug-reports and contributions around it.
+
+For connecting to GoldSrc-based servers, use this command:
+```
+connect ip:port gs
+```
+
+But keep in mind, there are requirement for server to be able to accept connections from Xash3D-based clients: it should use Reunion.
+Without this requirement, you will just get "Steam validation rejected" error on connecting.
+
+That is because proper authorization with Steam API is not implemented in engine yet (but we have plans on it).
+
+Also, we encountered that some GoldSrc-based servers are recognizing Xash3D clients as "fake clients" and banning/kicking them. Maybe this problem will be
+solved along with better compatibility with GoldSrc behavior, but may be not - we don't know logic behind this fake client checks.

+### HD (external) textures support
+
+Xash3D supports loading texture replacements in TGA format for almost all types of models in the game, except alias models at this time.
+
+Textures are expected to be located at:
+* `modfolder/materials/<mapname>` - for a specific map
+* `modfolder/materials/common` - common for all maps
+* `modfolder/materials/decals` - for decals
+* `modfolder/materials/models/<model>` - for models (texture name must match the internal texture name in the model)
+
+Support for high-resolution textures is enabled setting `host_allow_materials` cvar to `1` or in the menu, in "Video options" section.
+
+#### Xash3D FWGS additions
+
+In addition to paths above, Xash3D FWGS checks following paths:
+
+* `modfolder/materials/sprites/<sprite>` - for sprites, except HUD sprites
+
+Also, to check which texture replacements are loaded successfully, failed or weren't found, a mod developer can set `host_allow_materials` cvar value to `2`. The engine will spew log at any developer level in the following format:
+
+```
+Looking for <replacement> replacement... <status code> (<path relative to mod directory>)
+```
+
+Status codes:
+* `OK` - texture replacement file was found and loaded into GPU memory successfully
+* `FAIL` - texture file was found but hasn't been parsed or loaded successfully. Refer to engine log for more details.
+* `MISS` - texture file wasn't found
+
+Example:
+```
+Looking for maps/bounce.bsp:!waterblue tex replacement...OK (materials/common/!waterblue.tga)
+Looking for maps/bounce.bsp:!waterblue_luma tex replacement...MISS (not found)
+Looking for {shot2 decal replacement...MISS (materials/decals/{shot2.tga)

+# NAT bypass feature in Xash3D FWGS
+Since IPv6 not as widespread as we would like, NAT (Network Address Translation) still being actively used by many internet service providers in an attempts to
+mitigate IPv4 addresses exhaustion. In short, they uses one IPv4 address and doing some tricks with ports to represent many other users behind this address.
+
+But this leads to a problem for users: they cannot accept direct
+incoming connections anymore. This means that if you are behind provider's NAT and will try to setup Xash3D FWGS server - nobody will be able to connect to it,
+and the server will not show up in servers public list.
+
+## Is it possible to avoid this problem?
+In most cases, it is possible to bypass NAT with UDP hole punching, and Xash3D FWGS uses this method too. But this method is not 100% guaranteed to work - it depends
+on NAT configurations on both server and client side, and there is no way to control it.
+
+First of all, server should not be behind symmetric NAT. You can check your NAT type on [this page](https://www.checkmynat.com/).
+If you get "Symmetric NAT" result in this test, that means you cannot setup publicly available server with internet connection that you are using.
+
+Here is more detailed scheme of different NAT types compatibility, it explains are users with different NAT types can connect to each other or not.
+Client NAT type on rows, server NAT type on columns:
+
+| *NAT Type*           | Full Cone | Restricted Cone | Port Restricted Cone | Symmetric |
+| -------------------- | --------- | --------------- | -------------------- | --------- |
+| Full Cone            | ✔️        | ✔️              | ✔️                    | ✔️        | 
+| Restricted Cone      | ✔️        | ✔️              | ✔️                    | ✔️        |
+| Port Restricted Cone | ✔️        | ✔️              | ✔️                    | ❌        |
+| Symmetric            | ✔️        | ✔️              | ❌                   | ❌        |
+
+## How to use NAT bypass feature?
+If you are starting server within the game, you need to enable option "*Use NAT Bypass instead of direct mode*" in bottom left corner of screen.
+
+If you are starting dedicated server, you should add console variable `sv_nat 1` to server.cfg file, or add `+sv_nat 1` to server startup parameters.
+
+If you need to connect to server behind NAT, there is separate tab named *NAT* for such servers in server browser. Note that it is useless to add NAT server to favorites,
+or somehow trying manually to store it, because it has changing address and port.

 For additional info, run Xash3D with `-help` command line key.
