# Using Composer 1

Each Nitro site comes with Composer 2 installed by default. If you need to use Composer 1, you can SSH into the site and update it manually:

  1. Navigate to your project:
    $ cd ~/dev/my-craft-project
  2. SSH into your site’s container with all-powerful root user permissions:
    $ nitro ssh --root
  3. Update Composer to version 1:
    $ composer self-update --1
  4. Optionally exit your site’s container and return to your host machine:
    $ exit

Because site containers are ephemeral, you’ll need to do this again any time you rebuild its Docker container!
