-## Features
-
-Queuer is a queue manager, built on top of [OperationQueue](https://developer.apple.com/documentation/foundation/operationqueue) and [Dispatch](https://developer.apple.com/documentation/dispatch) (aka GCD). It allows you to create any asynchronous and synchronous task easily, all managed by a queue, with just a few lines.

 Setting the `maxConcurrentOperationCount` property of a queue to `1` will make you sure that only one task at a time will be executed.
 
-### Asynchronous Operation
+### Create a Custom Operation
 
-`ConcurrentOperation` is a class created to be subclassed.
+If you want to create your custom `Operation`, the class `ConcurrentOperation` is a class ready to be subclassed.
 It allows synchronous and asynchronous tasks, has a pause and resume states, can be easily added to a queue and can be created with a block.
 
 You can create your custom `ConcurrentOperation` by subclassing it.
 
-You must override `execute()` function and call the `finish(success:)` function inside it, when the task has finished its job to notify the queue.
-
-For convenience it has an `init` function with a completion block:
-
-```swift
-let concurrentOperation = ConcurrentOperation { _ in
-    /// Your task here
-}
-concurrentOperation.addToQueue(queue)
-```
+You must override `execute()` function and call the `finish(success:)` function, when the task has finished its job to notify the queue, regardless if it was successful or not.
