How-To Guides

A set of how-to guides demonstrating how to use Rel to solve concrete problems.

How-to guides are designed to guide you through the steps needed to take on specific tasks and problems. They are more advanced than Tutorials and assume some background knowledge of the Rel language and the RKGMS.
