+Policy Chaining
+===============
+
+The *usecases* controller supports chaining of multiple operations inside a Tosca Operational Policy. The next operation can be chained based on the result/output from an operation.
+The possibilities available for chaining are:
+
+- *success: chain after the result of operation is success*
+- *failure: chain after the result of operation is failure due to issues with controller/actor*
+- *failure_timeout: chain after the result of operation is failure due to timeout*
+- *failure_retries: chain after the result of operation is failure after all retries*
+- *failure_exception: chain after the result of operation is failure due to exception*
+- *failure_guard: chain after the result of operation is failure due to guard not allowing the operation*
