 ## Usage
 
+### Generate the proxy dll source
 .\DllProxyGenerator.exe "path\to\your\dll"
 
-Be careful which dlls you try to proxy. I tried public windows dlls like d3d9 or user32 whch work great. Game specific dlls with mangled function names wont work. Except someone knows how to counter this problem.

+
+### Build the proxy dll
+Create a new Visual Studio dll project. Copy the generated proxy files into your project.
+
+Remove every other file like stdafx.h
+
+Change the following settings.
+
+* General > Project Defaults > Character Set = Use Multi-Byte Character Set
+* C/C++ > Precompiled Headers > Precompiled Header = Not Using Precompiled Headers
+
+### Use the new dll
+Copy your new proxy inside the game directory. Some games have a different load mechanism. Depending on which dll you generated it could be possible that the game does not load your dll first in which case the proxy doesnt work.
