-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.

+| `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. 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. |

+# 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 accept HLTV connections.
+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).
+
+In case of ReHLDS with Reunion plugin, by default it rejects HLTV clients. But connections from HLTV can be easily enabled in `reunion.cfg` file.

+### 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)
+Looking for {shot4 decal replacement...MISS (materials/decals/{shot4.tga)
+Looking for {shot3 decal replacement...MISS (materials/decals/{shot3.tga)
+Looking for models/gman tex replacement...FAIL (materials/models/gman/GMan_Case1.tga)
+Looking for models/gman tex replacement...FAIL (materials/models/gman/inside_1.tga)
