+# Rocket.Chat
+
+## 产品介绍
+Rocket.Chat 是一套开源团队通信协作平台，支持频道、私聊、用户管理、集成和工作区协作。
+
+## 主要功能
+- 创建团队频道和私聊会话
+- 管理工作区用户、角色和权限
+- 支持机器人、Webhook 和应用集成
+
+## 访问说明
+安装后通过安装表单中的 `ROOT_URL` 访问。默认地址为 `http://<服务器 IP>:18087`，实际端口以 `PANEL_APP_PORT_HTTP` 为准。
+
+## Introduction
+Rocket.Chat is an open source team communication platform for channels, direct messages, user management, integrations and workspace collaboration.
+
+## Features
+- Create team channels and direct messages
+- Manage workspace users, roles and permissions
+- Use bots, webhooks and app integrations
+
+## 部署说明
+- 本应用基于官方 `rocketchat-compose` 的核心服务适配，包含 Rocket.Chat、MongoDB 单节点复制集和 NATS。
+- 当前固定使用 `registry.rocket.chat/rocketchat/rocket.chat:8.0.1`、`mongodb/mongodb-community-server:8.2-ubi8` 和 `nats:2.11-alpine`。
+- 应用分类：工具。
+- 支持架构：amd64、arm64。
+- 可选版本：`latest`，但镜像版本固定，避免自动跨版本升级。
+
+## 端口
+| 变量 | 说明 | 默认值 | 必填 |
+| --- | --- | --- | --- |
+| PANEL_APP_PORT_HTTP | HTTP 访问端口 | 18087 | 是 |
+
+## 数据持久化
+| 变量 | 说明 | 默认值 | 必填 |
+| --- | --- | --- | --- |
+| APP_DATA_DIR | MongoDB 数据目录 | ./data | 是 |
+
+升级、迁移或修改 MongoDB/Rocket.Chat 版本前，请先在 1Panel 中备份 `APP_DATA_DIR`。
+
+## 参数说明
+| 变量 | 说明 | 默认值 | 必填 |
+| --- | --- | --- | --- |
+| ROOT_URL | Rocket.Chat 对外访问地址，必须和真实访问协议、域名或端口保持一致 | http://127.0.0.1:18087 | 是 |
+| REG_TOKEN | Rocket.Chat Cloud 注册令牌，没有可留空 | 空 | 否 |
+| ADMIN_USERNAME | 初始管理员用户名 | admin | 是 |
+| ADMIN_NAME | 初始管理员显示名 | Admin | 是 |
+| ADMIN_EMAIL | 初始管理员邮箱 | admin@example.com | 是 |
+| ADMIN_PASS | 初始管理员密码 | 随机生成 | 是 |
+
+## 使用说明
+- 首次访问后，使用安装表单中的初始管理员信息登录并完成工作区设置。
+- 生产环境建议使用真实域名和 HTTPS 反向代理，并将 `ROOT_URL` 设置为最终访问地址。
+- Rocket.Chat 官方建议生产环境固定版本，不要使用浮动的 `latest` 标签。
+- Rocket.Chat 升级前必须阅读目标版本发布说明，确认 MongoDB 兼容版本，并按版本顺序升级；不要跳过大版本。
+- 本应用未加入 Renovate 自动合并白名单，后续升级需要人工审计 MongoDB、NATS 和 Rocket.Chat 版本兼容性，并执行真实升级测试。
