 In most cases, you may need to customize the server. For custom server you can read: [Custom Server](/custom-server.html#connect). When customizing the server, you don't need to register the middleware as a plugin, because you can use the middleware directly in your custom `Server`.
 
+In addition to registering `before:render` and `after:render` middleware, you can also register `before:setup` and `after:setup` middleware. The difference is that they are executed in a different order, as follows:
+
+```js
+// Execute from top to bottom
+before:setup
+before:render
+after:render
+after:setup
+```

+Middleware types `before:setup` and `after:setup` are only available in `@vapper/core@1.3.0+` versions.

 ## Register command
 
 A new `CLI` command can be registered via the plugin, and the `module.exports.CLI` function needs to be exported in the plugin module:

 大多数情况下，你可能需要自定义服务器，关于自定义服务器的内容可以阅读：[自定义 Server](/zh/custom-server.html#connect)。当自定义服务器时，你不需要以插件的形式注册中间件，因为你可以直接在你的自定义 `Server` 中使用相应的中间件即可。
 
+除了可以注册 `before:render` 和 `after:render` 类型的中间件外，还可以注册 `before:setup` 以及 `after:setup` 类型的中间件，它们的不同在于执行顺序，完整的执行顺序如下：
