If you are not familiar with using Composer to manage Drupal dependencies, read Using Composer with Drupal before continuing. Since you are already using the command line, we recommend you use Drush or Drupal console for various site management operations.
If you want to avoid using Composer for site management, the Ludwig module offers a manual alternative to Composer. In the Installing section, we document Ludwig installation; however, most of the documentation assumes that you will be using Composer to manage your site. If you do decide to use Ludwig instead of Composer, please be aware that updating and maintaining your site will be more difficult. Site administrators using Ludwig need to be careful when combining modules that depend on external libraries, since there are no safeguards against incompatible library versions or overlapping requirements.
