 **GoNavi** 是一款基于 **Wails (Go)** 和 **React** 构建的现代化、高性能、跨平台数据库管理客户端。它旨在提供如原生应用般流畅的用户体验，同时保持极低的资源占用。
 
 相比于 Electron 应用，GoNavi 的体积更小（~10MB），启动速度更快，内存占用更低。

 支持构建：
 *   macOS (AMD64 / ARM64)
 *   Windows (AMD64)
+*   Linux (AMD64，提供 WebKitGTK 4.0 与 4.1 变体产物)
+
+---
+
+## ❓ 常见问题 (Troubleshooting)
+
+### macOS 提示 "应用已损坏，无法打开"
+
+由于本项目尚未购买 Apple 开发者证书进行签名（Notarization），macOS 的 Gatekeeper 安全机制可能会拦截应用的运行。请按照以下步骤解决：
+
+1.  将下载的 `GoNavi.app` 拖入 **应用程序** 文件夹。
+2.  打开 **终端 (Terminal)**。
+3.  复制并执行以下命令（输入密码时不会显示）：
+    ```bash
+    sudo xattr -rd com.apple.quarantine /Applications/GoNavi.app
+    ```
+4.  或者：在 Finder 中右键点击应用图标，按住 `Control` 键选择 **打开**，然后在弹出的窗口中再次点击 **打开**。
+
+### Linux 启动报错缺少 `libwebkit2gtk` / `libjavascriptcoregtk`
+
+GoNavi 的 Linux 二进制依赖系统 WebKitGTK 运行库。不同发行版默认版本不同：
+
+- Debian 13 / Ubuntu 24.04 及更新版本：通常为 WebKitGTK 4.1
+- Ubuntu 22.04 / Debian 12 等：通常为 WebKitGTK 4.0
+
+如果启动时报错（如 `libwebkit2gtk-4.0.so.37: cannot open shared object file`），请按系统安装对应依赖后重试：
+
+```bash
+# Debian 13 / Ubuntu 24.04+
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.1-0 libjavascriptcoregtk-4.1-0
+
+# Ubuntu 22.04 / Debian 12
+sudo apt-get update
+sudo apt-get install -y libgtk-3-0 libwebkit2gtk-4.0-37 libjavascriptcoregtk-4.0-18
+```
+
+如果你使用的是 Release 中带 `-WebKit41` 后缀的 Linux 产物，请优先在 Debian 13 / Ubuntu 24.04+ 上使用；普通 Linux 产物更适合 WebKitGTK 4.0 运行环境。
