 #  ❄ idgenerator-V
 
+## 介绍
 
+项目更多介绍参照：https://github.com/yitter/idgenerator
+
+## 运行环境
+
+```sh
+$ v --enable-globals run test.v
+```
+
+## 调用示例（V）
+
+第1步，**全局** 初始化（应用程序启动时执行一次）：
+```v ignore
+// 定义全局变量
+__global ( idgen gen.YitIdHelper ) //定义全局变量
+
+// 使用默认参数配置
+idgen = gen.YitIdHelper{
+	id_gen: gen.make_generator(&contract.IdGeneratorOptions{})
+}
+
+// 更改配置参数
+idgen.set_id_generator(&contract.IdGeneratorOptions{
+	method: 1
+	base_time: 1582136402000
+	workerid_bitlength: 6
+	seq_bitlength: 10
+})
+
+//以上配置全局一次
+```
+
+第2步，生成ID：
+```v ignore
+// 初始化以后，即可在任何需要生成ID的地方，调用以下方法：
+newId := idgen.next_id()
+```
