+## Pure Debian Environment Example (Next.js)
+
+This is a “pure Debian 12” development environment on Sealos. It shows how to quickly set up and run a Next.js app inside a clean Debian system. The workflow feels just like local development—no need to manage Docker yourself.
+
+### Project Description
+The project provides a minimal yet practical developer experience: once in Devbox, install Node.js (via nvm) and create a Next.js sample. You can extend it to your own stack as needed.
+
+### Environment
+- OS: Debian 12 (bookworm)
+- Platform: Sealos Devbox (cloud-based, ready to use)
+- User & Privileges: default user `devbox` with passwordless `sudo`
+- Networking & SSH: `sshd` enabled, public key login supported
+- Package Mirrors: Tsinghua mirror (CN) supported for faster installs in Mainland China
+
+### Project Execution
+- Development mode (recommended): enter Devbox, then install Node.js (nvm) and run Next.js dev server.
+```bash
+# 1) Install nvm (recommended)
+curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
+export NVM_DIR="$HOME/.nvm" && [ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
+
+# 2) Install & use Node.js LTS (includes npm)
+nvm install --lts && nvm use --lts
+
+# 3) Create and start a Next.js sample
+npx create-next-app@latest my-next-app
+cd my-next-app
+npm run dev  # default port 3000
+```
+- Access: open the project’s public URL in Devbox, and make sure the port is set to 3000.
+
+- Production mode (optional): after development, build and run in production mode.
+```bash
+npm run build
+npm run start
+```
+
+### Devbox: Code. Run. Ship. We handle the rest.
+DevBox: Code. Build. Deploy. We've Got the Rest. With DevBox, you can focus entirely on writing great code while we handle the infrastructure, scaling, and deployment. Seamless development from start to production.
