 # `@vuepress-plume/vuepress-plugin-netlify-functions`
 
+
+If your vuepress site is deployed on `netlify` and you want to be able to use `netlify functions` for ` serverless`.
+
+You may need this plugin to provide support.
+
 如果你的 vuepress 站点是部署在 `netlify` 的，而且希望能够使用`netlify functions` 来做 `serverless`。
 
 那么你可能需要本插件提供支持。
 
+## Feature
+
+- On the Vuepress local server, start a `Netlify Functions` local service to help you debug `functions` locally.
+- Generate a usable `netlify.toml` and add the appropriate 'functions' configurations if you have already created` netlify.toml`
+- This plugin does not provide specific `function` scripts, only `netlify functions` support; It can be used directly in themes, directly in vuepress projects, or based on this plugin, new plugins can be developed to provide more detailed functionality support.
+- Use `dotenv` to provide support similar to `Netlify Environment variables` in the local service environment. Create `.env` files in the project root directory to hold development-time environment variables
+
 ## 功能
 - 在 vuepress 本地服务器上，启动一个 `netlify functions` 本地服务，帮助你在本地对 `functions` 进行调试。
 - 帮助生成一个 可用的 `netlify.toml` ，如果你已经创建了 `netlify.toml`，会添加合适的 `functions` 配置
