Sure — here’s a quick README section you can paste:

Install Docker + Docker Compose

This script auto-detects the OS and installs:

• Docker Engine
• Docker CLI
• containerd
• Docker Buildx plugin
• Docker Compose plugin

Supported OS families

• Ubuntu / Debian
• AlmaLinux / RHEL / Rocky / CentOS / Fedora

Run

chmod +x install_docker_compose.sh
sudo ./install_docker_compose.sh

What it does

• Detects the Linux distribution from /etc/os-release
• Adds Docker’s official package repository
• Installs the latest Docker packages
• Starts and enables the Docker service
• Verifies the install with:
  • docker --version
  • docker compose version

Notes

• Must be run as root or with sudo
• On Debian/Ubuntu, it installs from Docker’s official APT repo
• On Alma/RHEL-family systems, it installs from Docker’s official DNF repo

Verify manually

docker --version
docker compose version
sudo systemctl status docker

If you want, I can also turn that into a cleaner full README.md with a title, usage, supported platforms, and troubleshooting.
