-## Introduction
+## 🌟 What is NanoKVM?
 
-Lichee NanoKVM is an IP-KVM product based on LicheeRV Nano, inheriting the extreme size and powerful features of LicheeRV Nano.
+NanoKVM is a series of compact, open-source IP-KVM devices based on the LicheeRV Nano (RISC-V). NanoKVM allows you to remotely access and control computers as if you were sitting right in front of them – perfect for managing servers, embedded systems, or any headless machine.
 
-The Lichee NanoKVM is now available in three versions:
+## 📦 Product Family
 
-* NanoKVM-Cube Lite is a basic configuration that is suitable for individual users with certain DIY capabilities and enterprise users with bulk requirements.
+We offer several NanoKVM versions to suit your needs:
 
-* NanoKVM-Cube Full is a full version with a sophisticated case and complete accessories, as well as a built-in system mirror card that is ready to use at boot, and is recommended for individual users.
-
-* NanoKVM-PCle is a new form with a built-in PCle baffle that can be fixed inside the chassis. NanoKVM-PCle adds optional WiFi and PoE functions based on NanoKVM-Cube; it has its own PCle slot and can draw power from the motherboard PCle slot; in addition, the wired connection (ETH) is also more stable, meeting more professional needs.
+* **NanoKVM-Cube Lite:** A barebones kit for DIY enthusiasts and enterprise users requiring bulk deployment.
+* **NanoKVM-Cube Full:** A complete package featuring a sleek case, accessories, and a pre-flashed system SD card. Ready to use out-of-the-box; ideal for individual users.
+* **NanoKVM-PCIe:** A unique form factor with a PCIe bracket for internal chassis mounting. It draws power directly from the PCIe slot and supports optional WiFi and PoE functions.
+* **[NanoKVM-Pro:](https://github.com/sipeed/NanoKVM-Pro)** Based on popular demand, the **Pro version** delivers significant performance upgrades:
+  * **Resolution:** Upgraded from 1080P to stunning **4K@30fps / 2K@60fps**.
+  * **Network:** Blazing fast **1Gbps Ethernet + PoE + WiFi 6** ((upgraded from 100Mbps).
+  * **Latency:** Encoder accelerated latency reduced from 100-150ms to **50-100ms**.

-## Hardware platform NanoKVM
-
-NanoKVM is based on Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html)，you can find specifications, schematics, and dimensional drawings [here](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano).
+NanoKVM is based on Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html). You can find specifications, schematics, and dimensional drawings in the [download station](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano).
 
 The NanoKVM Lite is constructed by the LicheeRV Nano and HDMItoCSI board, and the NanoKVM FULL adds the NanoKVM-A/B board and shell to the NanoKVM Lite. The HDMItoCSI board is used to convert the HDMI signal; NanoKVM-A, including OLED, ATX control output (USB Type-C interface), auxiliary power supply and ATX power on/off and reset buttons; The NanoKVM-B is connected to the plate at one end and the computer at the other end is connected to the computer ATX-Pin, which is used to remotely control the power of the computer.

-
-## NanoKVM ハードウェアプラットフォーム
-
-NanoKVMはSipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html)に基づいており、仕様、回路図、寸法図は[こちら](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano)で確認できます。
-
-NanoKVM LiteはLicheeRV NanoとHDMItoCSIボードで構成され、NanoKVM FULLはNanoKVM LiteにNanoKVM-A/Bボードとシェルを追加しています。HDMItoCSIボードはHDMI信号を変換するために使用されます。NanoKVM-AにはOLED、ATX制御出力（USB Type-Cインターフェース）、補助電源供給およびATX電源オン/オフおよびリセットボタンが含まれています。NanoKVM-Bは一端がAボードに接続され、他端がコンピュータのATXピンに接続され、コンピュータの電源をリモートで制御します。
-
-NanoKVMイメージはLicheeRV Nano SDKおよびMaixCDKに基づいて構築されており、LicheeRV Nanoを使用する資料と互換性があります。逆に、KVMソフトウェアはLicheeRV Nanoや他のSG2002製品では使用できません。LicheeRV NanoやMaixCamでHDMI入力アプリケーションを構築したい場合は、技術サポートを受けるためにお問い合わせください。
-
-注：SG2002の256MBメモリのうち、現在158MBがマルチメディアサブシステムに割り当てられており、NanoKVMはビデオ画像の取得と処理にこのメモリを使用します。

-## NanoKVM 硬件平台
-
-NanoKVM 基于 Sipeed [LicheeRV Nano](https://wiki.sipeed.com/hardware/zh/lichee/RV_Nano/1_intro.html) 核心板搭建，这部分硬件的规格书、原理图、尺寸图等均可在这里找到：[点击这里](http://cn.dl.sipeed.com/shareURL/LICHEE/LicheeRV_Nano)
-
-NanoKVM Lite 由 LicheeRV Nano E 和 HDMItoCSI 小板构成，NanoKVM FULL 在 NanoKVM Lite 基础上增加 NanoKVM-A/B 板和外壳。HDMItoCSI板用于转换HDMI信号；NanoKVM-A 包含 OLED、ATX控制输出（TypeC接口形式）、辅助供电（TypeC接口）以及ATX开关机、复位按键；NanoKVM-B 一端连接A板，一端连接电脑ATX针脚，用于电脑的远程开关机。
-
-NanoKVM 镜像在LicheeRV Nano SDK 和 MaixCDK 基础上构建，可以兼容使用 LicheeRV Nano 的资料，反之LicheeRV Nano 或其他 SG2002 产品无法使用KVM软件。如果您想在 LicheeRV Nano 或 MaixCam 上构建 HDMI输入相关应用，请与我们联系，以获得技术支持。
-
-注: SG2002的256MB内存中, 目前划分105MB用于多媒体子系统, NanoKVM会在视频图像采集和处理中使用这部分内存.

-If you want to set your own static ip address

-Then you need to create a file \`/boot/eth.nodhcp\`,

-    \`addr/netid        gw[optional]\` in one line
-    for example (support muti definations, checks with arp):
-    1. 192.168.0.101/24 192.168.0.1
-    2. 192.168.3.116/22
-Delete this file if you change to use dhcp default.
-ATTENTION: If all the STATIC address you set in the file is
-    already in use on this LAN checked with arp, then none
-    of them will be yours. And it will trigger dhcp, try to 
-    fetch DYNAMIC one. If it's also failed, your address will 
-    be the REVERSE one, 192.168.0.1/24. Just to be sure that
-    you can visit your NanoKVM device through eth to fix some
-    problems by ssh, unless you must disassemble it and modify
-    or rewrite the TFCard once again.

-如果您想自行设置静态 ip 地址而不是使用 dhcp 来获取它。
-
-那么您需要新建一个文件 \`/boot/eth.nodhcp\`，然后按照以下格式编辑它：
-    \`addr/netid        gw[optional]\` 在一行内
-示例（支持多个预设，会通过 arp 检查是否占用）：
-    1. 192.168.0.101/24 192.168.0.1
-    2. 192.168.3.116/22
-
-如果您想改回默认 dhcp 获取 ip 地址的方式，删除该文件后即可恢复。
-
-注意：如果您预设的所有静态 ip 地址都被 arp 检测到已占用，则不会成功设置。
-    此时会触发 dhcp 尝试获取 ip 地址，如果仍失败，那么最终会强制设置成
-    192.168.90.1/24。这是为了保证您的 NanoKVM 设备总是能有一个可用的
-    ip 地址，方便您通过局域网 ssh 连接设备进行一些修复，否则您可能需要
-    拆开外壳以手动修改 TF 卡或重新烧卡。

-  3. Your NanoKVM device must keep online.
-
-Then, follow the steps below:
-  1. Login in https://login.tailscale.com on your PC
-     to enter into yout admin console.
-  2. Run 'tailscale login' on your device, and copy the link showed
-     to open on your PC, and confirm the auth.
-  3. Congratulations, your NanoKVM device is now on the tailnet, try to
-     visit it from all your device which on the same tailnet.
-  4. run 'tailscale set --webclient' and manage your device
-     on the web interface from localnet and tailenet.
-
-Added: no more action to be repeat after your device reboot.

-为了正常使用 tailscale, 你需要满足以下几个条件：
-  1. tailscale 和 tailscaled 这两个静态链接的二进制程序
-     都已经正确安装在系统上。
-  2. 至少注册一个 tailscale 的帐号才能使用其服务。
-     (https://login.tailscale.com/start)
-  3. 你的 NanoKVM 设备必须保持在线。
-
-然后，跟着以下步骤操作：
-  1. 在你的电脑上登录 https://login.tailscale.com 以进入控制台。
-  2. 在你的 NanoKVM ssh 终端上执行 'tailscale login', 然后复制
-     出现的链接到浏览器上，登录并通过验证。
-  3. 祝贺，你的 NanoKVM 现在已经加入了 tailnet 然后你可以从任意
-     同样已加入同一 tailnet 的设备去访问你的 NanoKVM。
-  4. 执行 'tailscale set --webclient' 然后你就可以从 '局域网' 和
-     'tailnet' 来访问特定网页，用来管理你的设备。
-
-补充: 不需要重复上面的操作，哪怕你的设备重启过。
