+# 使用Docker部署Perplexity AI代理服务
+
+本教程将指导您如何使用Docker来部署Perplexity AI代理服务。
+
+## 前提条件
+
+1. 安装Docker和Docker Compose
+   - 对于Windows和Mac用户,安装 [Docker Desktop](https://www.docker.com/products/docker-desktop)
+   - 对于Linux用户,按照[官方文档](https://docs.docker.com/engine/install/)安装Docker和Docker Compose
+
+2. 获取Perplexity AI的Cookie和User-Agent
+   - 按照 `usage.md` 中的说明获取这些信息
+
+## 部署步骤
+
+1. 克隆或下载项目代码到本地
+
+2. 在项目根目录创建一个 `.env` 文件,内容如下:
+
+   ```
+   PPLX_COOKIE=your_perplexity_cookie_here
+   USER_AGENT=your_user_agent_here
+   API_TOKEN=your_api_token_here
+   all_proxy=your_proxy_here  # 如果需要使用代理,否则可以省略
+   ```
+
+   将 `your_perplexity_cookie_here`, `your_user_agent_here`, 和 `your_api_token_here` 替换为您的实际值。
+
+   对于 `all_proxy`，您可以使用以下格式之一：
+   - HTTP 代理：`http://host:port`
+   - HTTPS 代理：`https://host:port`
+   - SOCKS4 代理：`socks4://host:port`
+   - SOCKS5 代理：`socks5://host:port`
+
+   例如：`all_proxy=http://192.168.3.13:39999`
+
+3. 打开终端,进入项目根目录
+
+4. 构建Docker镜像:
+
+   ```
+   docker-compose build
+   ```
+
+5. 启动服务:
+
+   ```
+   docker-compose up -d
+   ```
+
+6. 服务现在应该在后台运行。您可以通过以下命令查看日志:
+
+   ```
+   docker-compose logs -f
+   ```
+
+7. 要停止服务,运行:
+
+   ```
+   docker-compose down
+   ```
+
+## 使用服务
+
+服务启动后,它将在 `http://localhost:8081` 上运行。您可以按照 `usage.md` 中的说明配置您的客户端使用这个地址。
+
+## 故障排除
+
+1. 如果遇到权限问题,尝试在命令前加上 `sudo`
+
+2. 确保端口8081没有被其他服务占用
+
+3. 如果服务无法连接到Perplexity AI,检查您的Cookie是否有效,以及是否需要配置代理
+
+4. 如果使用代理，确保代理地址格式正确且代理服务器可用
+
+5. 查看Docker日志以获取更多错误信息:
+   ```
+   docker-compose logs
+   ```
+
+如果仍然遇到问题,请查看项目的issue页面或创建新的issue寻求帮助。

+# 使用方法
+
+1. 获得一个 Perplexity 账户并且订阅，登录。
+
+2. 打开 F12（DevTools），找到 “Network（网络）”、刷新一下页面，找到“www.perplexity.ai”这个项目
+
+3. 点进去，往下滑找到 "Cookie"，完整的复制后面的内容。
+
+4. 用同样的方法找到 "User-Agent"，完整的复制后面的内容。
+
+5. 下载或Clone本项目代码，解压
+
+6. 编辑 `start.bat` 文件，把上面的 Cookie 和 User Agent 粘贴进去
+
+7. 启动 start.bat （Linux/macOS用户使用 start.sh）
+
+8. 酒馆中选择 Claude，反向代理地址填 http://127.0.0.1:8081/v1。反代密码必须填，随便什么都可以。
+
+9. 开始使用。如果失败了/没有结果/403/Warning 就多重试几次。
+
+# 使用代理
+
+可以使用本地的socks5或http(s)代理。只需在 start.bat 中设置 `all_proxy` 环境变量。
+
+比如，如要使用 Clash 的默认本地SOCKS5代理，则应设置为 `set all_proxy=socks5://127.0.0.1:7890`
+
+## 注意事项
+
+出现 403 错误请重新抓 COOKIE 或者更换代理出口 IP。
+
+# Usage
+
+1. Get a Perplexity account and subscribe, log in.
+
+2. Open F12 (DevTools), find “Network”, refresh the page, and find “www.perplexity.ai”.
+
+3. Click on it, scroll down and find “Cookie:”, and copy the entire contents.
+
+4. Find the "user-agnet" in the same way.
+
+5. Download or Clone the code of this project and unzip it.
+
+6. Edit the `start.bat` file and paste the cookie and User Agent into it.
+
+7. Start start.bat
+
+8. Select Claude in the Tavern and put http://127.0.0.1:8081/v1 as the address of the reverse proxy. Use any random string for password.
+
+9. Enjoy it. If it fails/no result/403/Warning, try again.
+
+# Use custom proxy
+
+Use the `all_proxy` env to set custom proxy. Refer to https://www.npmjs.com/package/proxy-from-env for detail.
+
+## Caution
+
+If you get 403 errors, consider getting the cookie again or changing your IP.
