+
+`gf` 是一个强大的 CLI 工具，用于便捷地构建 [GoFrame](https://goframe.org) 应用程序。
+
+## 1. 安装
+
+## 1) 预编译二进制文件
+
+您也可以使用预构建的二进制文件安装 `gf` 工具：<https://github.com/gogf/gf/releases>
+
+1. `Mac` & `Linux`
+
+   ```shell
+    wget -O gf https://github.com/gogf/gf/releases/latest/download/gf_$(go env GOOS)_$(go env GOARCH) && chmod +x gf && ./gf install -y && rm ./gf
+   ```
+
+   > 如果您使用 `zsh`，您可能需要通过命令 `alias gf=gf` 重命名别名以解决 `gf` 和 `git fetch` 之间的冲突。
+
+2. `Windows`
+   手动下载，在命令行中执行，然后按照说明操作。
+
+3. 数据库支持
+
