- * A cluster pool with a min/max number of workers, is possible to execute tasks in sync or async mode as you prefer.

- * when the max number of workers is reached, an event will be emitted, if you want to listen this event use the emitter method.
+ * This cluster pool creates new workers when the others are busy, up to the maximum number of workers.
+ * When the maximum number of workers is reached, an event is emitted. If you want to listen to this event, use the pool's `emitter`.
