+# Luo Tianyi CodeLab AI Agent
+
+提供类似 QQ 界面的公共 AI 聊天机器人，基于 Google Gemini 模型。
+
+**注意**
+ - 不支持视频、图片、音频等多模态输入。
+ - 完全公开、无频率限制与身份认证。建议使用免费的 API Key 并禁用结算账号。
+ - 暂时没有列出所有模型的功能。
+
+## 使用方法
+从 GitHub Release 下载最新版本的压缩包，解压缩。你可以使用 `-h` 参数查看帮助信息：
+```bash
+./ai-agent-web -h
+```
+
+要正常启动服务器，您需要设置环境变量 `GOOGLE_AI_KEY`。您可以在 [Google AI Studio](https://aistudio.google.com) 免费获得一个（需要 Google 账号）。
+```bash
+export GOOGLE_AI_KEY=your-key
+./ai-agent-web
+```
+
+您也可以使用 Docker 运行：
+```bash
+docker run -d -p 57120:7120 -e GOOGLE_AI_KEY=your-key \
+    --name ai-agent-web ghcr.io/ltylab/codelab-ai-agent
+```
+
+如果需要自定义 AI Agent，请将您的 AI Agent 配置文件映射到 `/app/agents` 目录：
+```bash
+docker run -d -p 57120:7120 -e GOOGLE_AI_KEY=your-key \
+    -v /path/to/your/agents:/app/agents \
+    --name ai-agent-web ghcr.io/ltylab/codelab-ai-agent
+```
+
+可以通过 `-model` 参数修改模型，推荐使用下面两个免费模型：
+ - `gemini-1.5-flash`
+ - `gemini-2.0-flash-exp`
+
+## 配置文件
+AI Agent 内置了一些默认的 AI Agent，但您也可以自定义 AI Agent。
+
+AI Agent 的配置文件目录结构如下：
+```
+agents
+`- <AgentID>  Agent ID, 必须由小写字母、数字、横线组成，且 2-80 个字符
+    |- agent.json          配置文件
+    |- avatar.webp         头像
+    |- system_prompt.txt   系统提示
+    `- initial_prompt.txt  初始提示
+```
+
+下面是一个配置文件的示例：
+```json
+{
+    "id": "luo",
+    "name": "洛天依AI",
+    "desc": "世界第一的 ∞ 吃货殿下～",
+    "primaryColor": "#6cb6df",
+    "secondaryColor": "#66ccff",
+    "accentColor": "#a62f35"
+}
+```
+
+其中：
+ - `id` 是 Agent ID，必须和文件夹名称一致。
+ - `name` 是 Agent 名称，将显示在聊天界面。
+ - `desc` 是 Agent 描述，将显示在聊天界面。
+ - `primaryColor` 是主色调，将用于聊天界面的背景色。可选，如果未设置则使用默认值。
+ - `secondaryColor` 是次色调，将用于聊天界面的背景色。可选，如果未设置则使用默认值。
+ - `accentColor` 是强调色，将用于聊天界面的背景色。可选，如果未设置则使用默认值。
