    It is reliable, but can take significant time (minutes to hours) and space (megabytes to a gigabyte) depending on your connection, machine and past installations.
    You can add `--dry-run` to see what it plans to do, and kill/restart it without losing progress.\
    You can omit the bracketed packages to save time, and maybe install them later. If you include them, don't type the brackets.
