+## 使用说明
+
+    本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK4、MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用数据线连接开发板到 PC，打开电源开关。
+
+#### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
+
+> 工程默认配置使用AT-LINK SWD下载程序，在通过AT-LINK SWD连接开发板的基础上，点击下载按钮即可下载程序到开发板
+
+#### 运行结果
+
+下载程序成功之后，系统会自动运行，观察开发板上 LED 的运行效果，LED2/3/4 会周期性闪烁。
+
+连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，在串口上可以看到 RT-Thread 的输出信息:
+
+```bash

+## 使用说明
+
+    本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK4、MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用数据线连接开发板到 PC，打开电源开关。
+
+#### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
+
+> 工程默认配置使用AT-LINK SWD下载程序，在通过AT-LINK SWD连接开发板的基础上，点击下载按钮即可下载程序到开发板
+
+#### 运行结果
+
+下载程序成功之后，系统会自动运行，观察开发板上 LED 的运行效果，LED2/3/4 会周期性闪烁。
+
+连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，在串口上可以看到 RT-Thread 的输出信息:
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     4.1.0 build May 11 2022
+ 2006 - 2022 Copyright by RT-Thread team
+msh />
+```
+
+## 注意事项
+
+可在雅特力官方网站进行所需资料下载，如Keil_v5/Keil_v4/IAR等pack安装包和AT-START开发板原理图等（www.arterytek.com）
