<<<EOT
The require command adds required packages to your composer.json and installs them.
If you do not specify a package, composer will prompt you to search for a package, and given results, provide a list of
matches to require.
If you do not specify a version constraint, composer will choose a suitable one based on the available package versions.
If you do not want to install the new dependencies immediately you can call it with --no-update
