 # Debian Network Reinstall Script
 
-[General description in English ↓](#introduction)
-
-## VPS 网络重装 Debian 12 脚本
-
-**暂不支持 Oracle Linux 作为原系统。创建新机器时请选择 Ubuntu 系统模板。**
-
-下载脚本：
-
-```
-curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh && chmod a+rx debi.sh
-```
-
-运行脚本：
-
-```
-sudo ./debi.sh --cdn --network-console --ethx --bbr --user root --password <新系统用户密码>
-```
-
-* `--bbr` 开启 BBR
-* `--ethx` 网卡名称使用传统形式，如 `eth0` 而不是 `ens3`
-* `--cloud-kernel` 安装占用空间较小的 `cloud` 内核，但可能会导致 UEFI 启动的机器（如 Oracle、Azure 及 Hyper-V、Google Cloud 等）VNC 黑屏。BIOS 启动的普通 VPS 则没有此问题。
-* 默认时区为 UTC，添加 `--timezone Asia/Shanghai` 可使用中国时区。
-* 默认使用 Debian 官方 CDN 镜像源（deb.debian.org），添加 `--china` 可使用阿里云镜像源。
-
-如果没有报错可以重启：
-
-```
-sudo shutdown -r now
-```
-
-约 30 秒后可以尝试 SSH 登录 `installer` 用户，密码与之前设置的相同。如果成功连接，可以按 Ctrl-A 然后再按 4 监控安装日志。安装完成后会自动重启进入新系统。

 ## Introduction
 
-This script is written to reinstall a VPS/virtual machine to minimal Debian 10/11/12.
+This script is written to reinstall VPS/VMs to minimal Debian.
 
-## Should Work On
+## Platforms
 
-### Virtualization Platform
-
- * SolusVM/OpenStack/DigitalOcean/Vultr/Linode/Proxmox/QEMU KVM (BIOS boot)
- * Oracle Cloud Infrastructure (UEFI boot)
- * Google Cloud Compute Engine (**Must manually configure the VPC internal IP and the gateway.** UEFI boot with Secure Boot support)
- * AWS EC2 & Lightsail (BIOS boot)
- * Hyper-V & Azure (Generation 1 BIOS boot & Generation 2 UEFI boot)
-
-### Original OS
-
- * Debian 8 or later
- * Ubuntu 14.04 or later
- * CentOS 7 or later
+- ✔ KVM or physical machines ❌ Containers
+- ✔ Debian or Ubuntu or Red Hat Linux as original OS with GRUB 2 bootloader
+- ✔ MBR or GPT partition table
+- ✔ Multiple disks or LVM
+- ✔ IPv4 or IPv6
+- ✔ Legacy BIOS or UEFI boot
+- ✔ Most VPS or cloud providers
+- ⚠️ Google Compute Engine - **MUST** manually specify IP/CIDR and gateway of VPC
+- ⚠️ AWS EC2 or Lightsail - Does **NOT** work with UEFI boot
