Several resources are available for instructors wanting to use WeBWorK as a part of their course
The WeBWorK Quickstart Guide is intended to give some handy tips to
instructors using WeBWorK at Dartmouth. The guide was written by
Rebecca Weber.
The WeBWorK Newbie Guilde is a now
somewhat outdated (but occasionally useful) introduction to the design
of WeBWorK problems.
The MAA is now the official repository of all WeBWorK materials. Instructor tutorials and other documentation is available on their wiki page.
