 ### 快速使用：
 
 1. 指定一个token，在多台设备上运行该程序，例如：
     ```shell
       # linux上
-      root@DESKTOP-0BCHNIO:/opt# ./switch-desktop start --token 123456
+      root@DESKTOP-0BCHNIO:/opt# ./vnt-cli -k 123456
       # 在另一台linux上使用nohup后台运行
-      [root@izj6cemne76ykdzkataftfz switch]# nohup ./switch-desktop start --token 123456 &
+      root@izj6cemne76ykdzkataftfz vnt# nohup ./vnt-cli -k 123456 &
       # windows上
-      D:\switch\bin_v1>switch-desktop.exe start --token 123456
+      D:\vnt\bin_v1>vnt-cli.exe -k 123456
     ```
-2. 可以执行status命令查看当前设备的虚拟ip

 3. 也可以执行list命令查看其他设备的虚拟ip

 ### 使用须知
+
 - token的作用是标识一个虚拟局域网，当使用公共服务器时，建议使用一个唯一值当token(比如uuid)，否则有可能连接到其他人创建的虚拟局域网中
-- 建议指定deviceId，默认使用MAC地址，在某些环境下可能发生变化
-- 公共服务器目前的配置是2核4G 4Mbps，有需要再扩展~
+- 默认使用公共服务器，目前的配置是2核4G 4Mbps，有需要再扩展~
 - 需要root/管理员权限
-- 使用命令行运行
-- Mac和Linux下需要加可执行权限(例如:chmod +x ./switch-macos)
-- 自己搭注册和中继服务器(https://github.com/lbl8603/switch-server)
+- vnt-cli需要使用命令行运行
+- Mac和Linux下需要加可执行权限(例如:chmod +x ./vnt-cli)

 ### 常见问题
+<details> <summary>展开</summary>
+    
 #### 问题1: 设置网络地址失败
+
 ##### 可能原因:
-switch默认使用10.26.0.0/24网段，和本地网络适配器的ip冲突
+
+vnt默认使用10.26.0.0/24网段，和本地网络适配器的ip冲突
+
 ##### 解决方法:
+
 1. 方法一：找到冲突的IP，将其改成别的
 2. 方法二：自建服务器，指定其他不会冲突的网段
-3. 方法三：增加参数--device-id，设置不同的id会让switch-server分配不同的IP，从而绕开有冲突的IP
+3. 方法三：增加参数-d <device-id> ，设置不同的id会让服务端分配不同的IP，从而绕开有冲突的IP
+
+#### 问题2: windows系统上wintun.dll加载失败
+
+##### 可能原因：
+没有下载wintun.dll 或者使用的wintun.dll有问题
+##### 解决方法：
+1. 下载最新版的wintun.dll [下载链接](https://www.wintun.net/builds/wintun-0.14.1.zip)
+2. 解压后找到对应架构的目录,通常是amd64
+3. 将对应的wintun.dll放到和vnt-cli同目录下（或者放到C盘Windows目录下）
+4. 再次启动vnt-cli

+## 模块介绍
+体积小，可以在服务器、路由器等环境使用
+## 详细参数说明
+### -k
+一个虚拟局域网的标识，在同一服务器下，相同token的设备会组建一个局域网
+### -n
+设备名称，方便区分不同设备
+### -d
+设备id，每台设备的唯一标识，注意不要重复
+### -c
+关闭控制台交互式命令，后台运行时可以加此参数
+### -s
+注册和中继服务器地址，注册和转发数据
+### -e
+探测客户端NAT类型，不同类型有不同的打洞策略
+### -a
+加了此参数表示使用tap网卡，默认使用tun网卡，tun网卡效率更高
+### -i、-o
+
+配置点对网(IP代理)时使用，例如A(虚拟ip:10.26.0.2)通过B(虚拟ip:10.26.0.3,本地出口ip:192.168.0.10)访问C(目标网段192.168.0.0/24)，
+
+则在A配置 **-i 192.168.0.0/24,10.26.0.3** ,表示将192.168.0.0/24网段的数据都转发到10.26.0.3节点
+
+在B配置 **-o 192.168.0.0/24,192.168.0.10**  ,表示允许将192.168.0.0/24的数据从网卡192.168.0.10转发出去
+
+### -w
+提升通信安全性，使用该密码生成的密钥对客户端数据进行加密，并且服务端无法解密。使用相同密码的客户端才能通信
+
+### -m
+模拟组播，高频使用组播通信时，可以尝试开启此参数，默认情况下会把组播当作广播发给所有节点
+
+默认情况(组播当广播发送)：稳定性好，使用组播频率低时更省流量
+
+模拟组播：高频使用组播时防止广播泛洪，客户端和中继服务器会维护组播成员等信息，注意使用此选项时，虚拟网内所有成员都需要开启此选项
+
+### -u
+
+设置虚拟网卡的mtu值，大多数情况下使用默认值效率会更高，也可根据实际情况微调这个值，默认值为1430
