+# Installation
+
+1. <b>For users who use go1.18 and above, it is recommended to install lancet v2.x.x. Cause in v2.x.x all functions was rewriten with generics of go1.18.</b>
+
+```go
+go get github.com/duke-git/lancet/v2 // will install latest version of v2.x.x
+```
+
+2. <b>For users who use version below go1.18, you should install v1.x.x. The latest of v1.x.x is v1.4.1. </b>
+
+```go
+go get github.com/duke-git/lancet // below go1.18, install latest version of v1.x.x
+```
+
+
+## Usage
+
+Lancet organizes the code into package structure, and you need to import the corresponding package name when use it. For example, if you use string-related functions, just import the strutil package like below:
+
+```go
+import "github.com/duke-git/lancet/v2/strutil"
+```
+
+## Example
+
+Here takes the string function `Reverse` (reverse order string) as an example, and the strutil package needs to be imported.
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/duke-git/lancet/v2/strutil"
+)
+
+func main() {
+    s := "hello"
+    rs := strutil.Reverse(s)
+    fmt.Println(rs) //olleh
+}
+```

+# 安装
+
+1. <b>使用 go1.18 及以上版本的用户，建议安装 v2.x.x。 因为 v2.x.x 应用 go1.18 的泛型重写了大部分函数。</b>
+
+```go
+go get github.com/duke-git/lancet/v2 // will install latest version of v2.x.x
+```
+
+2. <b>使用 go1.18 以下版本的用户，必须安装 v1.x.x。目前最新的 v1 版本是 v1.4.1。</b>
+
+```go
+go get github.com/duke-git/lancet // below go1.18, install latest version of v1.x.x
+```
+
+## 用法
+
+lancet 是以包的结构组织代码的，使用时需要导入相应的包名。例如：如果使用字符串相关函数，需要导入 strutil 包:
+
+```go
+import "github.com/duke-git/lancet/v2/strutil"
+```
+
+## 示例
+
+此处以字符串工具函数 Reverse（逆序字符串）为例，需要导入 strutil 包:
+
+```go
+package main
+
+import (
+    "fmt"
+    "github.com/duke-git/lancet/v2/strutil"
+)
+
+func main() {
+    s := "hello"
+    rs := strutil.Reverse(s)
+    fmt.Println(rs) //olleh
+}
+```
+
+## More
+
+其他特性请参考[API](https://lancet.go.dev/api/overview.html).
