 ### ZCode Plugin Marketplace Install
 
-The root `marketplace.json` exposes this repository as a ZCode plugin marketplace, with the plugin manifest at `.zcode-plugin/plugin.json`. In ZCode, open **Settings → Plugins**, choose **Create → Add Marketplace**, enter `woooooooooolf/ser2mcp`, then install and enable `ser2mcp`.
+The root `marketplace.json` exposes this repository as a ZCode plugin marketplace, with the plugin manifest at `.zcode-plugin/plugin.json`. In ZCode, open **Settings → Plugins**, choose **Create → Add Marketplace**, enter the full repository URL `https://github.com/woooooooooolf/ser2mcp`, then install and enable `ser2mcp`.
 
 Installation loads all `uart_*` MCP tools and both repository SKILLs. Verify with `uart_list_ports`; an empty array still means the server is working, with no serial ports currently enumerable. For offline installation, add the repository directory as a local marketplace source.

 安装后会自动加载全部 `uart_*` MCP 工具和仓库内的两个 SKILL。调用 `uart_list_ports` 验证；返回空数组也表示服务器已正常工作，只是当前没有可枚举串口。离线安装时可把仓库目录作为本地市场源。
