 ## Introduction
 
 Lichee NanoKVM is an IP-KVM product based on LicheeRV Nano, inheriting the extreme size and powerful features of LicheeRV Nano.
-The Lichee NanoKVM is available in two versions:
-NanoKVM Lite is a basic configuration that is suitable for individual users with certain DIY capabilities and enterprise users with bulk requirements.
-The NanoKVM 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.

+The Lichee NanoKVM is now available in three versions:
+
+* NanoKVM-Cube Lite is a basic configuration that is suitable for individual users with certain DIY capabilities and enterprise users with bulk requirements.
+
+* 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.

+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。

-## If you want to compile kvm_system yourself, please follow the steps below: 
+# NanoKVM Support Instructions
 
-1. Clone the MaixCDK repository: `git clone https://github.com/sipeed/MaixCDK.git`
-2. Improve the Compilation Environment, refer to [here](https://github.com/sipeed/MaixCDK/tree/main/docs/doc_zh#%E5%BF%AB%E9%80%9F%E5%BC%80%E5%A7%8B)
-3. Copy `./kvm_system` to `~/MaixCDK` and open it in terminal
-4. Execute `maixcdk build` and Select `maixcam` to complete the compilation
-5. Replace `/kvmapp/kvm_system/kvm_system` in the NanoKVM system with `dist/kvm_system_release/kvm_system`
-6. Execute: `/etc/init.d/S95nanokvm restart` on NanoKVM
+`/support` contains auxiliary functions for NanoKVM, such as image subsystem, system status monitoring, system updates, screen key drivers, and a few system functions.
+
+Currently, NanoKVM is divided into two versions based on the main control chip: SG2002 (which includes NanoKVM-Lite/Full/PCIe) and H618 (including NanoKVM-Pro). Different chips have significantly different projects and compilation environments. To distinguish between them, they are stored separately in `/support/sg2002` and `/support/h618`.

+# NanoKVM Support Instructions
+
+## Environment Preparation
+1. NanoKVM-Lite/Full/PCIe is based on the SG2002 as the main control chip. The projects in the support section are compiled under the [MaixCDK](https://github.com/sipeed/MaixCDK) framework. Before compiling, please ensure that the `MaixCDK` environment is correctly configured. For configuration instructions, click [here](https://github.com/sipeed/MaixCDK/blob/main/docs/doc_zh/README.md).
+
+## kvm_system Compilation Instructions
+
+> The `kvm_system` is responsible for monitoring the NanoKVM system status, system updates, screen key drivers, and a few system functions, compiled with MaixCDK.
+
+1. Before compiling, please ensure that the above-mentioned `MaixCDK` environment is correctly configured.
+2. Modify the paths of `MAIXCDK_PATH` and `NanoKVM_PATH` in `./build`.
+3. Execute `./build kvm_system` to compile `kvm_system`.
+4. Use `scp ./kvm_system/dist/kvm_system_release/kvm_system root@192.168.x.x:/kvmapp/kvm_system` to copy it to NanoKVM for testing.
+5. Use `./build add_to_kvmapp` to place the executable file into the `/kvmapp` installation package.
+6. Use `./build kvm_system clean` to clean the compilation of `kvm_system`.
+
+## kvm_vision Compilation Instructions
+
+> `kvm_vision` refers to the image acquisition and encoding subsystem of NanoKVM, compiled with MaixCDK to produce dynamic libraries for Go calls. Use `kvm_vision_test` to compile and test the dynamic library.
+
+1. Before compiling, please ensure that the above-mentioned `MaixCDK` environment is correctly configured.
+2. Modify the paths of `MAIXCDK_PATH` and `NanoKVM_PATH` in `./build`.
+3. Execute `./build kvm_vision` to compile `kvm_vision_test`.
+4. You can test the dynamic libraries in `kvm_vision_test/dist/kvm_vision_test_release/dl_lib/`.
+5. Use `./build add_to_kvmapp` to place the dynamic libraries into the `/kvmapp` installation package.
+6. Use `./build kvm_vision clean` to clean the compilation of `kvm_vision`.
