 ## 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。
+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。

 ## 为什么选择OpenP2P
-### 免费
-完全免费，满足大部分用户的核心白票需求。不像其它类似的产品，我们不需要有公网IP的服务器，不需要花钱买服务。了解它原理即可理解为什么能做到免费。
-### 安全
-代码开源，接受各位大佬检验。下面详细展开
-### 轻量
+### 1. 免费
+完全免费，满足大部分用户的核心白票需求。不像其它类似的产品，OpenP2P不需要有公网IP的服务器，不需要花钱买服务。了解它原理即可理解为什么能做到免费。
+### 2. 共享
+你的设备会形成一个私有P2P网络，它们之间共享带宽，提供网络数据转发服务。
+当你的私有P2P网络下没有可以提供转发服务的节点时，会尝试在公共P2P网络寻找转发节点。
+默认会开启共享限速10mbps，只有你用户下提供了共享节点才能使用别人的共享节点。这非常公平，也是这个项目的初衷。
+我们建议你在带宽足够的地方（比如办公室，家里的百兆光纤）加入共享网络。
+如果你不想共享任何节点，或设置共享带宽，请查看[详细使用说明](/USAGE-ZH.md)
+### 3. 安全
+代码开源，P2P隧道使用TLS1.3+AES双重加密，共享节点临时授权使用TOTP一次性密码
+
+[查看详细](#安全性)
+### 4. 轻量
 文件大小2MB+，运行内存2MB+；全部在应用层实现，没有虚拟网卡，没有内核程序
-### 跨平台
+### 5. 跨平台
 因为轻量，所以很容易支持各个平台。支持主流的操作系统：Windows,Linux,MacOS；和主流的cpu架构：386、amd64、arm、arm64、mipsle、mipsle64、mips、mips64
-### 高效
+### 6. 高效
 P2P直连可以让你的设备跑满带宽。不论你的设备在任何网络环境，无论NAT1-4（Cone或Symmetric），都支持。依靠Quic协议优秀的拥塞算法，能在糟糕的网络环境获得高带宽低延时。

 基于OpenP2P只需数行代码，就能让原来只能局域网通信的程序，变成任何内网都能通信

 ## 快速入门

 ## 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.
+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
-### Free
-Totaly free, fullfills most of users(especially free-rider). Unlike other similar products, we don't need a server with public IP, and don't need to pay for services.By understanding its principle, you can understand why it can be done for free.
+### 1. Free
+Totaly free, fullfills most of users(especially free-rider). Unlike other similar products, OpenP2p doesn't need a server with public IP, and doesn't need to pay for services.By understanding its principle, you can understand why it can be done for free.
+### 2. Share
+Your devices will form a private P2P network, share bandwidth between them, and provide network data forwarding services.
+When there is no node that can provide forwarding services in your private P2P network, you will try to find forwarding nodes in the public P2P network.
+10mbps is its default setting of share speed limit. Only when you have shared their nodes, you are allowed to use others' shared nodes. This is very fair, and it is also the original intention of this project.
+We recommend that you join a shared network in a place with sufficient bandwidth (such as an office or home with 100M optical fiber).
+If you are not willing to contribute any node to the OpenP2P share network, please refer to the [usage](/USAGE.md) for your own setting.
+### 3. Safe
+The code is open source, the P2P tunnel uses TLS1.3+AES double encryption, and the shared node temporarily authorizes the use of the TOTP one-time password
+  
+[details](#Safety)

-### Safe
-Open source, trustable(see details below)
-
-### Lightweight
+### 4. Lightweight
 2MB+ filesize, 2MB+ memory. It runs at appllication layer, no vitrual NIC, no kernel driver.

-### Cross-platform
+### 5. Cross-platform
 Benefit from lightweight, it easily supports most of major OS, like Windows, Linux, MacOS, also most of CPU architecture, like 386、amd64、arm、arm64、mipsle、mipsle64、mips、mips64.

-### Efficient
+### 6. Efficient
 P2P direct connection lets your devices make good use of bandwidth.  Your device can be connected in any network environments, even supports NAT1-4 (Cone or Symmetric). Relying on the excellent congestion algorithm of the Quic protocol, high bandwidth and low latency can be obtained in a bad network environment.

-### Integration
+### 7. Integration
 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 .
-Under the outbreak of covid-19 pandemic, surely remote work becomes a fundamental demand.
+Just 4 simple steps to use.
+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.
-   ```
-   netstat -nl | grep 22
-   ```
-   Output sample
-   ![image](/doc/images/officelisten_linux.png)
+   ![image](/doc/images/install_en.png)

-2. Download the latest version of [OpenP2P](https://github.com/openp2p-cn/openp2p/releases),unzip the downloaded package, and execute below command line.
-   ```
-   tar xvf openp2p0.95.3.linux-amd64.tar.gz
-   ./openp2p install -node OFFICEPC1 -user USERNAME1 -password PASSWORD1
-   ```
+### 3.New P2PApp

-   > :warning: **Must change the parameters marked in uppercase to your own**
+![image](/doc/images/devices_en.png)

-   Output sample
-   ![image](/doc/images/officeexecute_linux.png)
+![image](/doc/images/newapp_en.png)

-3. Download the same package of [OpenP2P](https://github.com/openp2p-cn/openp2p/releases) on your home device，unzip and execute below command line.
-   ```
-   openp2p.exe -d -node HOMEPC123 -user USERNAME1 -password PASSWORD1 --peernode OFFICEPC1 --dstip 127.0.0.1 --dstport 22 --srcport 22022 --protocol tcp
-   ```
-   
-   > :warning: **Must change the parameters marked in uppercase to your own**
+![image](/doc/images/newappedit_en.png)

-   Output sample  
-   ![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)
+### 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/p2pappok_en.png)
+
+On MyHomePC, press Win+R and enter MSTSC to open the remote desktop, input `127.0.0.1:23389 /admin`
+
+   ![image](/doc/images/mstscconnect_en.png)
+
+   ![image](/doc/images/afterconnect_en.png)


-4. Test the connection between office device and home device.In your home deivce, run SSH to login the office device. 
-   ```
-   ssh -p22022 root@127.0.0.1:22022
-   ```

-10mbps is its default setting of share speed limit. Only when your users have shared their nodes, they are allowed to use others' shared nodes. This is very fair, and it is also the original intention of this project.

 ## Safety
 The nodes which have joined the OpenP2P share network can vist each other by authentications. Shared nodes will only relay data, and others cannot access any resources in the intranet.

-### TLS1.3+AES
+### 1. TLS1.3+AES
 The communication data between the two nodes uses the industry's most secure TLS1.3 channel. The communication content will also use AES encryption, double security, the key is exchanged through the server. Effectively prevent man-in-the-middle attacks.

-### Will the shared node capture my data?
+### 2. Will the shared node capture my data?
 That's right, the relay node is naturally an man-in-middle, so AES encryption is added to ensure the security of the communication content. The relay node cannot obtain the plaintext.
-### How does the shared relay node verify the authority?
+### 3. How does the shared relay node verify the authority?
 The server side has a scheduling model, which calculate  bandwith, ping value,stability and service duration to provide a well-proportioned service to every share node. It uses TOTP(Time-based One-time Password) with hmac-sha256 algorithem, its theory as same as the cellphone validation code or bank cipher coder.
