 * `isGlobal`: `boolean` 默认 `true` 。指示 Koishi-Nest 模块是否应被注册为全局模块，建议开启。当安装了其他模块的情况下，需要将 Koishi-Nest 注册为全局模块使得其他模块可以正常注入 Koishi-Nest 作为依赖项。 **异步配置该项应写入异步配置项中。** 关于全局模块请参考 [Nest.js 文档](https://docs.nestjs.cn/8/modules?id=%e5%85%a8%e5%b1%80%e6%a8%a1%e5%9d%97) 。

+## WebSocket
+
+Koishi-Nest 针对 Koishi 的 WebSocket 功能进行了针对 Nest.js 的适配。
+
+若要使用 Koishi 的与 WebSocket 服务器相关的插件或功能，需要在 Koishi-Nest 配置项中，把 `useWs` 设置为 `true` ，并在 `main.ts` 修改下列部分。
+
+```ts
+  const app = await NestFactory.create(AppModule);
+  app.useWebSocketAdapter(new KoishiWsAdapter(app));
+```
+
 ## 注入 Koishi 实例

 可以直接注入 Koishi 实例或上下文进行注册操作。这种情况下，建议让 Nest 提供者实现 `OnModuleInit` 接口，并在该事件方法中进行 Koishi 指令注册操作。
