+***gMod***
+
+Continuation of the uMod project to improve performance and stability. Integrated with [Guild Wars Launcher](https://github.com/gwdevhub/gwlauncher) and [Daybreak](https://github.com/gwdevhub/Daybreak).
+
+*Usage is primarily intended with GW Launcher or Daybreak, but it can be used without.*
+
+**Usage with manual gMod.dll injection:**
+- Create a file called modlist.txt in either the Guild Wars (Gw.exe) folder, or the gMod.dll folder.
+- Inject gMod.dll before d3d9.dll is loaded.
+
+**Usage without dll injection:**
+- Create a file called modlist.txt in the Guild Wars (Gw.exe) folder.
+- Place gMod.dll in the Guild Wars folder
+- Rename gMod.dll to d3d9.dll
+- Launch Guild Wars
+
+**Format of the modlist.txt file:**
+
+Each line in the modlist.txt is the full path to a mod you want to load (eg. `D:\uMod\Borderless Cartography Made Easy 2015 1.3.tpf`)
+gMod will load all these files on startup
+
+**Disclaimer about [Reshade](https://github.com/crosire/reshade)**
+
+Reshade in versions > 5.0.1 is known to cause glitches with TexMod, uMod and also gMod.
+If you would like to use Reshade in combination with gMod, we recommend running version [5.0.1](https://github.com/crosire/reshade/releases/tag/v5.0.1) or [4.9.1](https://github.com/crosire/reshade/releases/tag/v4.9.1).
+
+**Build from source**
+
+Requirements:
+- Visual Studio 2022
+- CMake 3.16+, integrated into the Developer Powershell for VS 2022
+- vcpkg, integrated into the Developer Powershell for VS 2022
+
+Compile:
+- cmake --preset=vcpkg
+- cmake --open build
+- compile
+
+**TpfConvert**
+Small utility to convert old .tpf files with invalid images into .zip files with working images.
+Usage:
+- put TpfConvert.exe and d3dx9.dll anywhere
+- create a folder "plugins" in that folder and put your .tpf/.zip files with invalid images there
+- run TpfConvert.exe, My_Texmod.tpf is fixed and copied into My_Texmod_.zip
+- copy My_Texmod_.zip into your GW Launcher plugins folder, delete My_Texmod.tpf from it, if it still exists

-The hash function is CRC32 using polynomial 0xEDB88320.
-However, the hashed data is calculated incorrectly in TexMod: it's simply BytesPerPixel * Width * Height, from the beginning of the data (that is mapped using LockRect).
-The problem is that it doesn't take the pitch into account and BytesPerPixel may be wrong for some rare formats (not sure about that).
