 h3. List containers
 
 @GET /arvados/v1/dispatch/containers@
 
 Return a list of containers that are either ready to dispatch, or being started/monitored by the dispatcher.
 
-The response provides @uuid@, @priority@, and @state@ fields for each container. Other fields of the container records are not loaded by the dispatcher, and will have empty/zero values here (e.g., @{...,"created_at":"0001-01-01T00:00:00Z","command":[],...}@).
+Each entry in the returned list of @items@ includes:
+* an @instance_type@ entry with the name and attributes of the instance type that will be used to schedule the container (chosen from the @InstanceTypes@ section of your cluster config file); and
+* a @container@ entry with selected attributes of the container itself, including @uuid@, @priority@, @runtime_constraints@, and @state@.
