+# GoLang Colorized Output
+
+GoLang colorized output library for Mac & Linux Shell, [中文版说明](README_CN.md)
+
+## Showcase
+![img](showcase.jpg)
+
+## Install
+
+1. __Make sure__ your've read [GoLang Official File Structure](https://golang.org/doc/code.html)
+2. Make sure you've set a correct GOPATH
+3. `$ go get github.com/bclicn/color`
+4. In your script, `import "github.com/bclicn/color"` then call `color.Test()`
+5. Use `fmt.Println("Hello" + color.Red("World"))` to assemble a colorized output
+6. API examples available in `color-test.go`
+
+## Quick (brainless) Usage
+
+1. Download `color.go`
+2. Modify its `package color` to `package main`
+3. Put your script under the same directory and write `fmt.Println(Red("I'm red !!!"))`
+4. Run `go run color.go yourScript.go`
+5. Or build by `go build color.go yourScript.go`
+
+## A simple test script
+
+    package main
+
+    import (
+	    "fmt"
+	    "github.com/bclicn/color"
+    )
+
+    func main(){
+	    fmt.Println(color.Red("Red output"))
+	    color.Test()
+    }

+
+## 效果展示
+![img](showcase.jpg)
+
+## 安装
+
+1. __确保__你已经读过  [GoLang官方文件结构](https://golang.org/doc/code.html)
+2. 确保你的GOPATH环境变量正确
+3. `go get github.com/bclicn/color`
+3. 在你的脚本中,`import "github.com/bclicn/color"` 然后调用 `color.Test()`查看全部效果
+5. 使用`fmt.Println("Hello" + color.Red("World"))`进行彩色输出
+4. API调用示例在`color-test.go`
+
+## 快速(无脑)使用
+
+1. 下载`color.go`
+2. 将其第一行的`package color`改为`package main`
+3. 把你的脚本放在同一个文件夹下,直接调用如`fmt.Println(Red("I'm red !!!"))`
+4. 运行`go run color.go yourScript.go`
+5. 你也可以直接`go build color.go yourScript.go`
+
+## 快速调用示例
+
+    package main
+
+    import (
+	    "fmt"
+	    "github.com/bclicn/color"
