• git clone https://github.com/suegy/bwapi-mono-bridge2.git
• cd into bwapi-mono-bridge
• open the StarcraftBot solution from the starcraftbot folder with VS 2008 sp1
• edit the references of the starcraftbot project and remove bwapi-clr.dll and starcraftbotlib.dll
• add references to starcraftbotlib.dll and bwapi-clr.dll from the libs\client folder
• compile the project
• Copy everything from the libs\client folder and place them into bwapi-data\ai in your starcraft folder. (this is not essential, the bot can be run from anywhere on your system, as long as the required files are in the same place)
• copy starcraftbot.dll from your project bin folder to the bwapi-data\AI folder

To run the bot:

• launch the ClrAiModuleLoader by running ClrAiModuleLoader.exe (it should say connecting...)
• launch starcraft on the same computer (the bot should now say "waiting for match")
• start a custom match against the computer.
• the bot should print some stuff to the screen etc.
