 The CLI tool validates all inputs and provides helpful prompts to guide you through the configuration process, making it easy to manage complex setups without editing JSON files manually.
 
+### 6. Activate Command (Environment Variables Setup)
+
+The `activate` command allows you to set up environment variables globally in your shell, enabling you to use the `claude` command directly or integrate Claude Code Router with applications built using the Agent SDK.
+
+To activate the environment variables, run:
+
+```shell
+eval "$(ccr activate)"
+```
+
+This command outputs the necessary environment variables in shell-friendly format, which are then set in your current shell session. After activation, you can:
+
+- **Use `claude` command directly**: Run `claude` commands without needing to use `ccr code`. The `claude` command will automatically route requests through Claude Code Router.
+- **Integrate with Agent SDK applications**: Applications built with the Anthropic Agent SDK will automatically use the configured router and models.
+
+The `activate` command sets the following environment variables:
+
+- `ANTHROPIC_AUTH_TOKEN`: API key from your configuration
+- `ANTHROPIC_BASE_URL`: The local router endpoint (default: `http://127.0.0.1:3456`)
+- `NO_PROXY`: Set to `127.0.0.1` to prevent proxy interference
+- `DISABLE_TELEMETRY`: Disables telemetry
+- `DISABLE_COST_WARNINGS`: Disables cost warnings
+- `API_TIMEOUT_MS`: API timeout from your configuration
+
+> **Note**: Make sure the Claude Code Router service is running (`ccr start`) before using the activated environment variables. The environment variables are only valid for the current shell session. To make them persistent, you can add `eval "$(ccr activate)"` to your shell configuration file (e.g., `~/.zshrc` or `~/.bashrc`).

 #### Providers
 
 The `Providers` array is where you define the different model providers you want to use. Each provider object requires:

+### 5. Activate 命令（环境变量设置）
+
+`activate` 命令允许您在 shell 中全局设置环境变量，使您能够直接使用 `claude` 命令或将 Claude Code Router 与使用 Agent SDK 构建的应用程序集成。
+
+要激活环境变量，请运行：
+
+```shell
+eval "$(ccr activate)"
+```
+
+此命令会以 shell 友好的格式输出必要的环境变量，这些变量将在当前的 shell 会话中设置。激活后，您可以：
+
+- **直接使用 `claude` 命令**：无需使用 `ccr code` 即可运行 `claude` 命令。`claude` 命令将自动通过 Claude Code Router 路由请求。
+- **与 Agent SDK 应用程序集成**：使用 Anthropic Agent SDK 构建的应用程序将自动使用配置的路由器和模型。
+
+`activate` 命令设置以下环境变量：
+
+- `ANTHROPIC_AUTH_TOKEN`: 来自配置的 API 密钥
+- `ANTHROPIC_BASE_URL`: 本地路由器端点（默认：`http://127.0.0.1:3456`）
+- `NO_PROXY`: 设置为 `127.0.0.1` 以防止代理干扰
+- `DISABLE_TELEMETRY`: 禁用遥测
+- `DISABLE_COST_WARNINGS`: 禁用成本警告
+- `API_TIMEOUT_MS`: 来自配置的 API 超时时间
+
+> **注意**：在使用激活的环境变量之前，请确保 Claude Code Router 服务正在运行（`ccr start`）。环境变量仅在当前 shell 会话中有效。要使其持久化，您可以将 `eval "$(ccr activate)"` 添加到您的 shell 配置文件（例如 `~/.zshrc` 或 `~/.bashrc`）中。
