+
+[release]: https://git.unlock-music.dev/um/web/releases/latest
+
+### 自行构建
+
+- 环境要求
+  - nodejs (v16.x)
+  - npm
+
+1. 获取项目源代码后安装相关依赖：
+
+   ```sh
    npm install
+   npm ci
    ```
 
-### Compiles and hot-reloads for development
-```
-npm run serve
-```
+2. 然后进行构建：
 
-### Compiles and minifies for production
-```
+   ```sh
    npm run build
    ```
 
-### Run your tests
-```
-npm run test
-```
+   - 构建后的产物可以在 `dist` 目录找到。
+   - 如果是用于开发，可以执行 `npm run serve`。
 
-### Lints and fixes files
-```
-npm run lint
-```
+3. 如需构建浏览器扩展，构建成功后还需要执行：
 
-### Customize configuration
-See [Configuration Reference](https://cli.vuejs.org/config/).
+   ```sh
+   npm run make-extension
+   ```
