How do I make cs source maps

[etalns]

I've been looking around for some material on how to make cs source maps, is there anyone that knows of a site that gives a decent idea of how to give it a shot? I wanna try and remake some of the old maps from the original CS (some of the more basic ones to start with )

Any help is appreciated.

Richard Simmons might be able to help. He is a big fan of CS.

Open Steam. Open "Source SDK." There should be a link to valve-erc.com. Check that out for starters. BTW, I'm not much of a mod guru, so that's just a suggestion. I don't know if it will help you out.
