+
+    ```shell
+    D:\SMARTDNS
+    ├─etc
+    │  ├─default

+
+    Double-click `install.bat` in the `D:\smartdns\package\windows` directory for installation. Please enter the password for `WLS ubuntu` when input password.
+
+1. Configuration
+
+    Edit `smartdns.conf` configuration file in `D:\smartdns\etc\smartdns` directory, you can configure the upstream server to  smartdns. Refer to the `Configuration Parameters` for specific configuration parameters.  
+    In general, you only need to add `server [IP]:port`, `server-tcp [IP]:port` configuration items.  
+    Configure as many upstream DNS servers as possible, including servers at home and abroad. Please refer to the `Configuration Parameters` section for configuration parameters.  
+
+1. Start Service
+
+    Double-click `reload.bat` in the `D:\smartdns\package\windows` directory for reload. 
+
+1. Forwarding DNS request to SmartDNS
+
+    Modify the default DNS server for Windows to `127.0.0.1`, with these steps referred to [IP configuration](https://support.microsoft.com/en-us/help/15089/windows-change-tcp-ip-settings)
+
+1. Check if the service is configured successfully
+
+    Query domain name with `nslookup -querytype=ptr 0.0.0.0`  
+    Check if the `name` item in the command result is displayed as `smartdns` or `hostname`, such as `smartdns`
+
+    ```shell
+    pi@raspberrypi:~/code/smartdns_build $ nslookup -querytype=ptr 0.0.0.0
+    Server:         192.168.1.1
+    Address:        192.168.1.1#53

+
+1. 安装smartdns
+
+    下载安装包`smartdns.xxxxxxxx.x86_64.tar.gz`，并解压到D盘根目录。解压后目录如下：
+
+    ```shell
+    D:\SMARTDNS
+    ├─etc
+    │  ├─default
+    │  ├─init.d
+    │  └─smartdns
+    ├─package
+    │  └─windows
+    ├─src
+    └─systemd
+
+    ```
+
+    双击`D:\smartdns\package\windows`目录下的`install.bat`进行安装。要求输入密码时，请输入`WLS ubuntu`的密码。
+
+1. 修改配置
+
+    记事本打开`D:\smartdns\etc\smartdns`目录中的`smartdns.conf`配置文件配置smartdns。具体配置参数参考`配置参数`说明。  
+    一般情况下，只需要增加`server [IP]:port`, `server-tcp [IP]:port`配置项，
+    尽可能配置多个上游DNS服务器，包括国内外的服务器。配置参数请查看`配置参数`章节。
+
+1. 重新加载配置
+
+    双击`D:\smartdns\package\windows`目录下的`reload.bat`进行安装。要求输入密码时，请输入`WLS ubuntu`的密码。
+
+1. 将DNS请求转发的SmartDNS解析。
+
+    将Windows的默认DNS服务器修改为`127.0.0.1`，具体步骤参考[IP配置](https://support.microsoft.com/zh-cn/help/15089/windows-change-tcp-ip-settings)
+
+1. 检测服务是否配置成功。
+
+    使用`nslookup -querytype=ptr 0.0.0.0`查询域名  
+    看命令结果中的`name`项目是否显示为`smartdns`或`主机名`，如`smartdns`则表示生效  
+
+    ```shell
+    pi@raspberrypi:~/code/smartdns_build $ nslookup -querytype=ptr 0.0.0.0
+    Server:         192.168.1.1
