The full WebMake documentation is online here.
If you're a WebMake newbie, the recommended reading order is as follows:
First of all, read WebMake Concepts for a quick intro to the assumptions and concepts that are used in WebMake.
Next, read WebMake Operation for an overview of how WebMake operates.
Then, read How To Migrate to WebMake for a guide to bringing an existing, simple web site into WebMake.
After that, you can read the rest of the manual if you like; it's mostly reference text.
