My First Policy 

A good starting point is the My First Policy example. It describes a sales problem, to which policy can be applied. The example details the policy background, shows how to use the REST Editor to create a policy, and provides details for running the policies. The documentation can be found:

Decision Maker 

The domain Decision Maker shows a very simple policy for decisions. Interesting here is that the it creates a Docker image to run the policy and that it uses the APEX REST applications to update the policy on the-fly. It also has local context to remember past decisions, and shows how to use that to no make the same decision twice in a row. The documentation can be found:
