 > **PipelinR** is a lightweight command processing pipeline ❍ ⇢ ❍ ⇢ ❍ for your awesome Java app.
 
 PipelinR has been battle-proven on production as a service layer for some cool FinTech apps. PipelinR has helped teams switch from giant service classes handling all use cases to small handlers, each following the single responsibility principle. It's similar to a popular [MediatR](https://github.com/jbogard/MediatR) .NET library.
 
 ⚡ Tested and works with plain Java, Kotlin, Spring, and Jakarta EE.

 ## Pipeline
+
 A **pipeline** mediates between commands and handlers. You send commands to the pipeline. When the pipeline receives a command, it sends the command through a sequence of middlewares and finally invokes the matching command handler. `Pipelinr` is a default implementation of `Pipeline` interface.
 
 To construct a `Pipeline`, create an instance of `Pipelinr` and provide a list of command handlers:

 ```java
 Pipeline pipeline = new Pipelinr()

 ### Notification handling strategies
+
 The default implementation loops through the notification handlers and awaits each one. This ensures each handler is run after one another.
 
 Depending on your use-case for sending notifications, you might need a different strategy for handling the notifications, such running handlers in parallel.
 
 PipelinR supports the following strategies:
-* `an.awesome.pipelinr.StopOnException` runs each notification handler after one another; returns when all handlers are finished or an exception has been thrown; in case of an exception, any handlers after that will not be run; **this is a default strategy**.
-* `an.awesome.pipelinr.ContinueOnException` runs each notification handler after one another; returns when all handlers are finished; in case of any exception(s), they will be captured in an AggregateException.
-* `an.awesome.pipelinr.Async` runs all notification handlers asynchronously; returns when all handlers are finished; in case of any exception(s), they will be captured in an AggregateException.
-* `an.awesome.pipelinr.ParallelNoWait` runs each notification handler in a thread pool; returns immediately and does not wait for any handlers to finish; cannot capture any exceptions.
-* `an.awesome.pipelinr.ParallelWhenAny` runs each notification handler in a thread pool; returns when any thread (handler) is finished; all exceptions that happened before returning are captured in an AggregateException.
-* `an.awesome.pipelinr.ParallelWhenAll` runs each notification handler in a thread pool; returns when all threads (handlers) are finished; in case of any exception(s), they are captured in an AggregateException.
