+
+对说明文档我已经尽可能的修补，有些重要的地方我甚至已经写到了打包的配置文件里。
+
+已经写在 README 中的功能，都是**可用**的，经过**验证**的，并且我自己**每天**都在使用的。
+
+可能在某些场景中使用上效果并不是很出色，但那基本上是模型和工具的原因，比如用 Claude Code 的时候，有的模型就无法正确使用工具，比如 Gemini，就在 Claude Code 和 Codex 的下使用的相当扭捏，有时能完成大部分工作，但有时候却只说不做。
+
+目前来说 Claude 和 GPT-5 是目前使用各种第三方CLI工具运用的最好的模型，我自己也是多个账号做均衡负载使用。
+
+实事求是的说，最初的几个版本我根本就没有中文文档，我至今所有文档也都是使用英文更新让后让 Gemini 翻译成中文的。但是无论如何都不会出现中文文档无法理解的问题。因为所有的中英文文档我都是再三校对，并且发现未及时更改的更新的地方都快速更新掉了。

 ```
 
+## 使用 Docker Compose 运行
+
+1.  克隆仓库并进入目录：
+    ```bash
+    git clone https://github.com/luispater/CLIProxyAPI.git
+    cd CLIProxyAPI
+    ```
+
+2.  准备配置文件：
+    通过复制示例文件来创建 `config.yaml` 文件，并根据您的需求进行自定义。
+    ```bash
+    cp config.example.yaml config.yaml
+    ```
+    *（Windows 用户请注意：您可以在 CMD 或 PowerShell 中使用 `copy config.example.yaml config.yaml`。）*
+
+3.  启动服务：
+    -   **适用于大多数用户（推荐）：**
+        运行以下命令，使用 Docker Hub 上的预构建镜像启动服务。服务将在后台运行。
+        ```bash
+        docker compose up -d
+        ```
+    -   **适用于进阶用户：**
+        如果您修改了源代码并需要构建新镜像，请使用交互式辅助脚本：
+        -   对于 Windows (PowerShell):
+            ```powershell
+            .\docker-build.ps1
+            ```
+        -   对于 Linux/macOS:
+            ```bash
+            bash docker-build.sh
+            ```
+        脚本将提示您选择运行方式：
+        - **选项 1：使用预构建的镜像运行 (推荐)**：从镜像仓库拉取最新的官方镜像并启动容器。这是最简单的开始方式。
+        - **选项 2：从源码构建并运行 (适用于开发者)**：从本地源代码构建镜像，将其标记为 `cli-proxy-api:local`，然后启动容器。如果您需要修改源代码，此选项很有用。
+
+4. 要在容器内运行登录命令进行身份验证：
+    - **Gemini**: 
+    ```bash
+    docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --login
+    ```
+    - **Gemini Web**:
+    ```bash
+    docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI --gemini-web-auth
+    ```
+    - **OpenAI (Codex)**:
+    ```bash
+    docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --codex-login
+    ```
+    - **Claude**:
+    ```bash
+    docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --claude-login
+    ```
+    - **Qwen**:
+    ```bash
+    docker compose exec cli-proxy-api /CLIProxyAPI/CLIProxyAPI -no-browser --qwen-login
+    ```
+
+5.  查看服务器日志：
+    ```bash
+    docker compose logs -f
+    ```
+
+6.  停止应用程序：
+    ```bash
+    docker compose down
+    ```
+
