+Quality of Service
+==================
+
+Ocelot supports one QoS capability at the current time. You can set on a per ReRoute basis if you 
+want to use a circuit breaker when making requests to a downstream service. This uses the an awesome
+.NET library called Polly check them out `here <https://github.com/App-vNext/Polly>`_.
+
+Add the following section to a ReRoute configuration. 
+
+.. code-block:: json
+
+    "QoSOptions": {
+        "ExceptionsAllowedBeforeBreaking":3,
+        "DurationOfBreak":5,
+        "TimeoutValue":5000
+    }
+
+You must set a number greater than 0 against ExceptionsAllowedBeforeBreaking for this rule to be 
+implemented. Duration of break is how long the circuit breaker will stay open for after it is tripped.
+TimeoutValue means ff a request takes more than 5 seconds it will automatically be timed out. 
+
+If you do not add a QoS section QoS will not be used.
