This document provides instructions for how to set up your WeBWorK server as an LTI provider in D2L, which then simplifies the process of creating links to individual WeBWorK courses or assignments. As an instructor this can be performed at the course level, and will apply to all links created within the course. An administrator can do this at the system level so that it applies to all courses on the system, or all courses within an organizational unit.
