 The `ResiliencePipelineRegistry<TKey>` is designed to create and cache resilience pipeline instances. The registry also implements the `ResiliencePipelineProvider<TKey>`, allowing read-only access to pipelines.

 To register pipeline builders, use the `TryAddBuilder(...)` method. This method accepts a callback argument that configures an instance of `ResiliencePipelineBuilder` for the pipeline being defined. The registry supports both generic and non-generic resilience pipelines.
 
+> [!NOTE]
+> Please note that you do not have to call the `Build` method after you have set up your pipeline on the `builder` parameter of the `TryAddBuilder`. You can call the `Build` if you want but it is not necessary.

 - If an error occurs during reloading, the cached pipeline remains, and dynamic reloading stops.
-- You should not reuse the cancellation token when the pipeline is reloaded.
+- You should **not** reuse the cancellation token when the pipeline is reloaded.
