+# 勘智SDK驱动包
+
+## 1、介绍
+
+勘智SDK驱动包是一份RT-Thread上勘智K210处理器对应的外设驱动包，主要是对K210上提供的standalone sdk提
+供一份RT-Thread移植、包装，能够融合到RT-Thread系统中。
+
+### 1.1 目录结构
+
+| 名称 | 说明 |
+| ---- | ---- |
+| kendryte-standalone-sdk  | 勘智K210处理器的外设驱动包 |
+
+### 1.2 许可证
+
+许可证协议同kendryte-standalone-sdk的许可证
+
+### 1.3 依赖
+
+- RT-Thread 4.0+
+- K210 BSP
+
+## 2、如何使用
+
+正常的情况下，当使用K210 BSP时，这份外设驱动包就会自动使能。而驱动包本身在menuconfig中位于如下路径：
+
+```
+RT-Thread online packages
+    peripheral libraries and drivers --->
+        [*] the kendryte-sdk package for rt-thread
+```
+
+然后让 RT-Thread 的包管理器自动更新，或者使用 `pkgs --update` 命令更新包到 BSP 中。
