title: Install Drupal 8 Commerce with composer
body: <p>I want to install Drupal Commerce on my new D8, I do it with Composer like recommended in the guide here (<a href="https://docs.drupalcommerce.org/commerce2/developer-guide/install-update/installation" rel="nofollow noreferrer">https://docs.drupalcommerce.org/commerce2/developer-guide/install-update/installation</a>), but I get this :</p>
  <blockquote>
  <p>$ composer require drupal/commerce</p>
  <p>[InvalidArgumentException]   Could not find package drupal/commerce.</p>
  <p>Did you mean this?
  drupal/commerce_taxcloud</p>
  </blockquote>
  <p>I'm using Wamp64 on Windows 10, if it matters.
  Any idea what I'm doing wrong ?</p>
  <p>Thank you</p>
