+# GF-CLI
+English | [简体中文](README_ZH.MD)
+
+`gf` is a powerful CLI tool for building [GoFrame](https://goframe.org) application with convenience.
+
+## 1. Install
+
+> You might need setting the goproxy to make through building.
+
+1. Latest version
+    ```
+    go install github.com/gogf/gf/tool/gf@latest
+    ```
+1. Specified version
+    ```
+    go install github.com/gogf/gf/tool/gf@v1.16.0
+    ```
+1. Database `sqlite` and `oracle` are not support in `gf gen` command in default as it needs `cgo` and `gcc`, you can manually make some changes to the source codes and do the building.
+
+## 2. Commands
+```html
+$ gf
+USAGE
+    gf COMMAND [ARGUMENT] [OPTION]
+
+COMMAND
+    env        show current Golang environment variables
+    get        install or update GF to system in default...
+    gen        automatically generate go files for ORM models...
+    mod        extra features for go modules...
+    run        running go codes with hot-compiled-like feature...
+    init       initialize an empty GF project at current working directory...
+    help       show more information about a specified command
+    pack       packing any file/directory to a resource file, or a go file...
+    build      cross-building go project for lots of platforms...
+    docker     create a docker image for current GF project...
+    swagger    swagger feature for current project...
+    update     update current gf binary to latest one (might need root/admin permission)
+    install    install gf binary to system (might need root/admin permission)
+    version    show current binary version info
+
+OPTION
+    -y         all yes for all command without prompt ask
+    -?,-h      show this help or detail for specified command
+    -v,-i      show version information
+
+ADDITIONAL
+    Use 'gf help COMMAND' or 'gf COMMAND -h' for detail about a command, which has '...'
+    in the tail of their comments.
+```
+
+## 3. FAQ
+
+### 1). Command `gf run` returns `pipe: too many open files`
+
+Please use `ulimit -n 65535` to enlarge your system configuration for max open files for current terminal shell session, and then `gf run`.

+# GF-CLI
+[English](README.MD) | 简体中文
+
+`gf`是一款强大的[GoFrame](https://goframe.org)开发工具链，使得我们开发基于`GoFrame`框架的项目更加便捷。
+
+## 1. 安装
+
+1. 最新版本
+    ```
+    go install github.com/gogf/gf/tool/gf@latest
+    ```
+1. 指定版本
+    ```
+    go install github.com/gogf/gf/tool/gf@v1.16.0
+    ```
+> 注意：在`gf gen`命令中，由于`sqlite`和`oracle`数据库需要`cgo`和`gcc`支持，因此预编译的二进制中不提供对这两个数据库的支持，您需要手动修改源码，去掉对应源码文件中指定数据库类型的`import`注释后手动编译支持。
+
+## 2. 命令
+```html
+$ gf
+USAGE
+    gf COMMAND [ARGUMENT] [OPTION]
+
+COMMAND
+    env        show current Golang environment variables
+    get        install or update GF to system in default...
+    gen        automatically generate go files for ORM models...
+    mod        extra features for go modules...
+    run        running go codes with hot-compiled-like feature...
+    init       initialize an empty GF project at current working directory...
+    help       show more information about a specified command
+    pack       packing any file/directory to a resource file, or a go file...
+    build      cross-building go project for lots of platforms...
+    docker     create a docker image for current GF project...
+    swagger    swagger feature for current project...
+    update     update current gf binary to latest one (might need root/admin permission)
+    install    install gf binary to system (might need root/admin permission)
+    version    show current binary version info
+
+OPTION
+    -y         all yes for all command without prompt ask
+    -?,-h      show this help or detail for specified command
+    -v,-i      show version information
+
+ADDITIONAL
+    Use 'gf help COMMAND' or 'gf COMMAND -h' for detail about a command, which has '...'
+    in the tail of their comments.
+```
+
+## 3. 文档
+
+完善详尽的中文文档请参考`GoFrame`官网板块：[开发工具](https://itician.org/pages/viewpage.action?pageId=1114260)
+
+## 4. FAQ
+
+### 1). `gf run` 命令报错 `pipe: too many open files`
+
+请执行`ulimit -n 65535`命令扩展您当前终端会话支持的最大文件打开数，随后再执行`gf run`。需要注意的是该命令仅对当前终端会话有效。

+DESCRIPTION
+    The "build" command is most commonly used command, which is designed as a powerful wrapper for 
+    "go build" command for convenience cross-compiling usage. 
+    It provides much more features for building binary:
+    1. Cross-Compiling for many platforms and architectures.
+    2. Configuration file support for compiling.
+    3. Build-In Variables.

-
-`gf`是一款强大的[GoFrame](https://goframe.org)开发工具链，使得我们开发基于`GoFrame`框架的项目更加便捷。
-
-## 1. 安装
-
-1. 最新版本
-    ```
-    go install github.com/gogf/gf/tool/gf@latest
-    ```
-1. 指定版本
-    ```
-    go install github.com/gogf/gf/tool/gf@v1.16.0
-    ```
-> 注意：在`gf gen`命令中，由于`sqlite`和`oracle`数据库需要`cgo`和`gcc`支持，因此预编译的二进制中不提供对这两个数据库的支持，您需要手动修改源码，去掉对应源码文件中指定数据库类型的`import`注释后手动编译支持。
-

-## 3. 文档
-
-完善详尽的中文文档请参考`GoFrame`官网板块：[开发工具](https://itician.org/pages/viewpage.action?pageId=1114260)
-
-## 4. FAQ
-
-### 1). `gf run` 命令报错 `pipe: too many open files`
-
-请执行`ulimit -n 65535`命令扩展您当前终端会话支持的最大文件打开数，随后再执行`gf run`。需要注意的是该命令仅对当前终端会话有效。

-# GoFrame CLI Tool
-
-Powerful CLI tool for building [GoFrame](https://goframe.org) application with convenience.
-
-## 1. Install
-
-> You might need setting the goproxy to make through building.
-
-1. Latest version
-   
-   > Go version >= v1.16
-    ```
-    go install github.com/gogf/gf/tool/gf@latest
-    ```
-   > Go version <= v1.15
-    ```
-    go install github.com/gogf/gf/tool/gf
-    ```
-   
-1. Specified version
-   
-   > Go version >= v1.16
-    ```
-    go install github.com/gogf/gf/tool/gf@v1.16.0
-    ```
-1. Database `sqlite` and `oracle` are not support in `gf gen` command in default as it needs `cgo` and `gcc`, you can manually make some changes to the source codes and do the building.
-
-## 2. Commands
-```html
-$ gf
-USAGE
-    gf COMMAND [ARGUMENT] [OPTION]
-
-COMMAND
-    env        show current Golang environment variables

-    mod        extra features for go modules...
-    run        running go codes with hot-compiled-like feature...
-    init       initialize an empty GF project at current working directory...
-    help       show more information about a specified command
-    pack       packing any file/directory to a resource file, or a go file...
-    build      cross-building go project for lots of platforms...
-    docker     create a docker image for current GF project...
-    swagger    swagger feature for current project...
-    update     update current gf binary to latest one
-    version    show current binary version info
-
-OPTION
-    -y         all yes for all command without prompt ask
-    -?,-h      show this help or detail for specified command
-    -v,-i      show version information
-
-ADDITIONAL
-    Use 'gf help COMMAND' or 'gf COMMAND -h' for detail about a command, which has '...'
-    in the tail of their comments.
-```
-
-## 3. FAQ
-
-### 1). Command `gf run` returns `pipe: too many open files`
-
-Please use `ulimit -n 65535` to enlarge your system configuration for max open files for current terminal shell session, and then `gf run`.

-DESCRIPTION
-    The "build" command is most commonly used command, which is designed as a powerful wrapper for 
-    "go build" command for convenience cross-compiling usage. 
-    It provides much more features for building binary:
-    1. Cross-Compiling for many platforms and architectures.
-    2. Configuration file support for compiling.
-    3. Build-In Variables.

-    The "swagger" command parses the current project and produces swagger API description

-    watches the changes of go files of current project and reproduces the swagger files,
-    which is quite convenient for local API development.
-    If it fails in command "swag", please firstly check your system PATH whether containing
