What is the best source of documentation available for the HL SDK?
The code is just a mess and could take a long time to get a grasp of it because of this.

Take a look at this: https://github.com/SamVanheer/HLEnhanced

I documented and cleaned up the SDK quite a bit. Most engine functions and game interfaces are documented, so it makes things a lot easier.

If you're looking for the server engine functions documentation, you can find that here: https://github.com/SamVanheer/HLEnha...ngine/eiface.h
