This example shows a shell script that automates the installation of Docker on Linux Mint. It first checks for HTTPS transport support in APT, installs `apt-transport-https` if missing, then adds the Docker repository to the APT sources list and imports its GPG key. The script runs `sudo apt-get update` and installs `docker.io`, `cgroup-lite`, and `apparmor`, followed by adding the current user to the `docker` group. It uses standard Bash commands and the `apt-get` package manager API, with an alternative commented-out method referencing the curl-able installer from get.docker.com.
