+# 身份证号码验证器
+
+这是一个用于验证和提取身份证号码信息的 Go 语言包。它提供了功能强大的方法来检查身份证号码的有效性，并从中获取出生日期和年龄。
+
+## 功能
+
+- 验证身份证号码的合法性
+- 提取身份证号码中的出生日期
+- 计算根据出生日期得到的年龄
+
+## 使用方法
+
+### 安装
+
+使用 Go 模块管理，可以通过以下命令安装：
+
+```shell
+go get -u github.com/deloz/idcardnumber
+```
+
+### 示例
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/deloz/idcardnumber"
+)
+
+func main() {
+	id := "320124198701011234" // 这里替换为要验证的身份证号码
+
+	// 验证身份证号码合法性
+	err := idcardnumber.Validator(id)
+	if err != nil {
+		fmt.Println("Error:", err)
+		return
+	}
+
+	// 创建一个新的身份证号码对象
+	card := idcardnumber.New(id)
+
+	// 获取出生日期
+	birthday := card.Birthday()
+	fmt.Println("出生日期:", birthday)
+
+	// 计算年龄
+	age, err := card.Age()
+	if err != nil {
+		fmt.Println("Error:", err)
+		return
+	}
+	fmt.Println("年龄:", age)
+}
+```
