     - name - `string` - required, the name of the child application and must be unique between the child applications.
 
     - entry - `string | { scripts?: string[]; styles?: string[]; html?: string }` - required, The entry url of the child application.
 
-    - container - `string | HTMLElement` - required，A selector or Element instance of the container node of a micro application. Such as `container: '#root'` or `container: document.querySelector('#root')`。

+## Manually load micro applications
+
+It is suitable for scenarios where a micro application needs to be manually loaded / unloaded.
+
+::: tip
+Usually in this scenario, the micro application is a business component that can run independently without routing.
+Micro applications should not be split too fine, it is recommended to split according to the business domain. Functional units with close business associations should be made into one micro-application, and conversely, those with less close association can be considered to be split into multiple micro-applications.
+A criterion for judging whether the business is closely related: **Look at whether this micro application has frequent communication needs with other micro applications**. If it is possible to show that these two micro-applications are serving the same business scenario, it may be more appropriate to merge them into one micro-application.
+:::
+
+### `loadMicroApp(app, configuration?)`
+
+* Parameters
+  * app - `LoadableApp` - Required, basic information of micro application
+    * name - `string` - Required, the name of the micro application must be unique among the micro applications.
+    * entry - `string | { scripts?: string[]; styles?: string[]; html?: string }` - Required, the entry address of the micro application.
+    * container - `string | HTMLElement` - Required, selector or Element instance of the container node of the micro application. Such as `container: '#root'` or `container: document.querySelector('#root')`.
+    * props - `object` - Optional, the data that needs to be passed to the micro-application during initialization.
+
+  * configuration - `Configuration` - Optional, configuration information of the micro application
+
+    * sandbox - `boolean` | `{ strictStyleIsolation?: boolean }` - Optional, whether to enable the sandbox, the default is `true`.
+
+      When configured as `{strictStyleIsolation: true}`, it means that strict style isolation mode is enabled. In this mode, qiankun will wrap a [shadow dom](https://developer.mozilla.org/zh-CN/docs/Web/Web_Components/Using_shadow_DOM) node for each micro-application container, so as to ensure that the style of the micro application will not affect the whole world.
+
+    * singular - `boolean | ((app: RegistrableApp<any>) => Promise<boolean>);` - Optional, whether it is a single instance scenario, the default is `false`.
+
+    * fetch - `Function` - Optional, custom fetch method.
+
+    * getPublicPath - `(url: string) => string` - Optional
+
+    * getTemplate - `(tpl: string) => string` - Optional
+
+* 返回值 - `MicroApp` - Micro application examples

+  * loadPromise: Promise<null>;
+  * bootstrapPromise: Promise<null>;
+  * mountPromise: Promise<null>;
+  * unmountPromise: Promise<null>;
+  
+* Usage
+
+  Load a micro application manually.
+
+  If you need to support the main application to manually update the micro application, you need to export an update hook for the micro application entry:
+
+  ```ts
+  export function mount(props) {
+    renderApp(props);
+  }
+  
+  // Added update hook to allow the main application to manually update the micro application
+  export function update(props) {
+    renderPatch(props);
+  }
+  ```
+
+* Sample
+
+  ```jsx
+  import { loadMicroApp } from 'qiankun';
+  import React from 'react';
+  
+  class App extends React.Component {
+    
+    microApp = null;
+    
+    componentDidMount() {
+      this.microApp = loadMicroApp(
+    		{ name: 'app1', entry: '//localhost:1234', container: '#app1', props: { name: 'qiankum' } },
+  		);
+    }
+  
+    componentWillUnmount() {
+      this.microApp.unmount();
+    }
+  
+  	componentDidUpdate() {
+      this.microApp.update({ name: 'kuitos' });
+    }
+    
+  	render() {
+      return <div id="app1"></div>;
+    }
+  }
+  ```
+
+### `prefetchApps(apps, importEntryOpts?)`
+
+- Parameters
+  - apps - `AppMetadata[]` - Required - list of preloaded apps
+  - importEntryOpts - Optional - Load configuration
+  
+- Type
+  - `AppMetadata`
+    - name - `string` - Required - Application name
+    - entry - `string | { scripts?: string[]; styles?: string[]; html?: string }` - Required,The entry address of the microapp
+
+- Usage
+  
+  Manually preload the specified micro application static resources. Only needed to manually load micro-application scenarios, you can directly configure the `prefetch` attribute based on the route automatic activation scenario.
+  
+- Sample
+
+  ```ts
+  import { prefetchApps } from 'qiankun';
+  
+  prefetchApps([ { name: 'app1', entry: '//locahost:7001' }, { name: 'app2', entry: '//locahost:7002' } ])
+  ```
