+        "max_tasks": 3,           # 支持同时提交的总任务个数
+        "max_tasks_per_user": 1,  # 支持单个用户同时提交的任务个数
+        "use_image_create_prefix": true   # 是否使用全局的绘画触发词，如果开启将同时支持由`config.json`中的 image_create_prefix 配置触发
+    }
+}
+
+```
+注意：
+
+ - 配置项中 `group_app_map` 部分是用于映射群聊与LinkAI平台上的应用， `midjourney` 部分是 mj 画图的配置，可根据需要进行填写，未填写配置时默认不开启相应功能
+ - 实际 `config.json` 配置中应保证json格式，不应携带 '#' 及后面的注释
+ - 如果是`docker`部署，可通过映射 `plugins/config.json` 到容器中来完成插件配置，参考[文档](https://github.com/zhayujie/chatgpt-on-wechat#3-%E6%8F%92%E4%BB%B6%E4%BD%BF%E7%94%A8)
+
+## 插件使用
+
+> 使用插件中的知识库管理功能需要首先开启`linkai`对话，依赖全局 `config.json` 中的 `use_linkai` 和 `linkai_api_key` 配置；而midjourney绘画功能则只需填写 `linkai_api_key` 配置，`use_linkai` 无论是否关闭均可使用。具体可参考 [详细文档](https://link-ai.tech/platform/link-app/wechat)。
+
+完成配置后运行项目，会自动运行插件，输入 `#help linkai` 可查看插件功能。
+
+### 1.知识库管理功能
+
+提供在不同群聊使用不同应用的功能。可以在上述 `group_app_map` 配置中固定映射关系，也可以通过指令在群中快速完成切换。
+
+应用切换指令需要首先完成管理员 (`godcmd`) 插件的认证，然后按以下格式输入：
+
+`$linkai app {app_code}`
+
+例如输入 `$linkai app Kv2fXJcH`，即将当前群聊与 app_code为 Kv2fXJcH 的应用绑定。
+
+### 2.Midjourney绘画功能
+
+指令格式：
+
+```
+ - 图片生成: $mj 描述词1, 描述词2..
+ - 图片放大: $mju 图片ID 图片序号
+```
+
+例如：
+
+```
+"$mj a little cat, white --ar 9:16"
+"$mju 1105592717188272288 2"
+```
+
+注：开启 `use_image_create_prefix` 配置后可直接复用全局画图触发词，以"画"开头便可以生成图片。
