 ## OpenP2P是什么
-它是一个开源、免费、轻量级的P2P共享网络。任何设备接入OpenP2P，随时随地访问它们。相比BT网络用来共享文件，OpenP2P网络用来共享带宽。
+它是一个开源、免费、轻量级的P2P共享网络。你的设备将组成一个私有P2P网络，里面的设备可以直接访问其它成员，或者通过其它成员转发数据间接访问。如果私有网络无法完成通信，将会到公有P2P网络寻找共享节点协助通信。
+相比BT网络用来共享文件，OpenP2P网络用来共享带宽。
 我们的目标是：充分利用带宽，利用共享节点转发数据，建设一个远程连接的通用基础设施。

-相信很多人在疫情下远程办公是刚需。
-1. 先确认办公室电脑已开启远程桌面功能（如何开启参考官方说明https://docs.microsoft.com/zh-cn/windows-server/remote/remote-desktop-services/clients/remote-desktop-allow-access）

 ## What is OpenP2P
-It is an open source, free, and lightweight P2P sharing network. As long as any device joins in, you can access them anywhere. Compared with the BT network used to share files, the OpenP2P network is used to share bandwidth.
+It is an open source, free, and lightweight P2P sharing network. Your devices will form a private P2P network, in which devices can directly access other members, or indirectly access through other members forwarding data.
+If the private network cannot complete the communication, it will go to the public P2P network to find a shared node to assist in the communication. Compared with the BT network used to share files, the OpenP2P network is used to share bandwidth.
 Our goal is to make full use of bandwidth, use shared nodes to relay data, and build a common infrastructure for remote connections.
 ## Why OpenP2P
 ### 1. Free
@@ -30,52 +31,46 @@ P2P direct connection lets your devices make good use of bandwidth.  Your device
 Your applicaiton can call OpenP2P with a few code to make any internal networks communicate with each other.
 
 ## Get Started
-A common scenario to introduce OpenP2P: remote work. At home connects to office's Linux PC .
+Just 4 simple steps to use.
-Under the outbreak of covid-19 pandemic, surely remote work becomes a fundamental demand.
+Here's an example of remote work: connecting to an office Windows computer at home.
+  
+### 1.Register
+Go to <https://console.openp2p.cn> register a new user
 
-> :warning: all commands in this doc, Windows env uses "openp2p.exe", Linux env uses "./openp2p"
+   ![image](/doc/images/register_en.png)
- 
+### 2.Install
+Download on local and remote computers and double-click to run, one-click installation
 
-1. Make sure your office device(Linux) has opened the access of ssh.
+   ![image](/doc/images/install_en.png)
-   ```
-   netstat -nl | grep 22
-   ```
-   Output sample
-   ![image](/doc/images/officelisten_linux.png)
 
-2. Download the latest version of `OpenP2P` [Download Page](https://openp2p.cn/),unzip the downloaded package, and execute below command line.
+By default, Windows will block programs that have not been signed by the Microsoft's certificate, and you can select "Run anyway".
-   ```
-   tar xzvf ${PackageName}
-   ./openp2p install -node OFFICEPC1 -user USERNAME1 -password PASSWORD1
-   ```
 
-   > :warning: **Must change the parameters marked in UPPERCASE to your own. These 3 parameters must >= 8 charaters**
+   ![image](/doc/images/win10warn_en.png)
 
-   Output sample
+   ![image](/doc/images/stillrun_en.png)
-   ![image](/doc/images/officeexecute_linux.png)
-
-3. Download OpenP2P on your home device，unzip and execute below command line.
-   ```
-   openp2p.exe -d -node HOMEPC123 -user USERNAME1 -password PASSWORD1 -appname OfficeSSH -peernode OFFICEPC1 -dstip 127.0.0.1 -dstport 22 -srcport 22022 -protocol tcp
-   ```
    
-   > :warning: **Must change the parameters marked in UPPERCASE to your own**
+### 3.New P2PApp
 
-   Output sample  
+![image](/doc/images/devices_en.png)
-   ![image](/doc/images/homeconnect_windows.png)  
-   The log of `LISTEN ON PORT 22022 START` indicates P2PApp runs successfully on your home device, listing port is 22022. Once connects to local ip:port,127.0.0.1:22022, it means the home device has conneccted to the office device's port, 22.  
-   ![image](/doc/images/officelisten_2_linux.png)
 
+![image](/doc/images/newapp_en.png)
 
-4. Test the connection between office device and home device.In your home deivce, run SSH to login the office device. 
+![image](/doc/images/newappedit_en.png)
-   ```
+
-   ssh -p22022 [email protected]:22022
+### 4.Use P2PApp
-   ```
+You can see the P2P application you just created on the "MyHomePC" device, just connect to the "local listening port" shown in the figure below.
-   ![image](/doc/images/sshconnect.png)
+
+![image](/doc/images/p2pappok_en.png)
+
+On MyHomePC, press Win+R and enter MSTSC to open the remote desktop, input `127.0.0.1:23389 /admin`
