 The resilience extensibility is simple. You just expose extensions for `ResilienceStrategyBuilder` that use the `ResilienceStrategyBuilder.AddStrategy` methods.
 
+If you want to create a resilience strategy that works for both generic and non-generic builders you can use `ResilienceStrategyBuilderBase` as a target:
