-### Building
-
-#### Setting up the environment
-
-- Pull the latest code of the trunk.
-
-- Set up the [RK3568 default environment](https://gitee.com/openharmony/docs/blob/master/en/device-dev/quick-start/Readme-EN.md)
-
-#### Modify the code
-
-1. Pull the code signature component
-
-```
-cd base/security
-
-git clone https://gitee.com/openharmony-sig/security_code_signature.git
-
-mv security_code_signature code_signature
-```
-
-2. Modify the repositories on which the code signature component depends
-
-The [patches.json](patches/patches.json) file in the current repository describes the repositories and patches on which
-
-the code signature component depends. Install the required patches in the corresponding repositories base on the description in the file.
-
-#### Building
-
-```
-./build.sh --product-name rk3568 --ccache
-```

-### 构建指导
-
-#### 构建环境
-
-- 拉取主干最新代码。
-
-- 构建环境: [RK3568默认环境](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/quick-start/Readme-CN.md)
-
-#### 修改代码
-
-1.拉取代码签名部件
-
-```
-cd base/security
-
-git clone https://gitee.com/openharmony-sig/security_code_signature.git
-
-mv security_code_signature code_signature
-```
-
-2.修改代码签名部件依赖的相关仓
-
-代码签名仓下的 [patches.json](patches/patches.json) 中详细描述了代码签名部件依赖的仓以及patch，根据文件中描述依次在对应仓打上对应的patch即可。
-
-#### 编译
-
-```
-./build.sh --product-name rk3568 --ccache
-```
