title: How can I composer global require hirak/prestissimo (or anything else) to DDEV-Local? (DON'T: Use Composer 2)
body: <p>Edit: This question has gotten quite old and is no longer useful. Prestissimo isn't really useful any more now that Composer 2 is out. The way to use composer 2 in DDEV-Local v1.16 is <code>ddev config --composer-version=2</code>. In DDEV-Local v1.17 Composer 2 will be the default.</p>
  <p>Original question:</p>
  <p>I'd like to use <a href="https://github.com/hirak/prestissimo" rel="nofollow noreferrer">hirak/prestissimo</a> to speed up the downloads for my DDEV-Local composer builds on all my projects, but I don't know how to install it globally. How can I install it?</p>
