-## Overview
+Package `anhhuu/conexec` (**Concurrent Executor for Asynchronous Task Execution**) provides a Concurrent Executor that facilitates the concurrent execution of multiple tasks, managing its own task queue. It is designed to handle asynchronous task execution with controlled concurrency and a task queue to ensure efficient resource utilization.

+## Installation
 
-## Features
-
-- **Task Execution:** Execute tasks concurrently while respecting the specified maximum concurrent task limit.
-- **Task Queue:** Manage a task queue to handle tasks that exceed the current concurrency limit.
-- **Error Handling:** Capture and report errors during task execution.
-- **Task Response:** Retrieve responses and errors for each completed task.
