When renaming your project you'll need to re-create a new database.

This can easily be done with Docker, but before this script does it
please agree that it's ok for this script to delete your current
project's database(s) by removing any associated Docker volumes.

We're done here. Everything worked!

If you're happy with your new project's name you can delete this
script by running: rm bin/rename-project

Or you can keep it around in case you decide to change your project's
name later on after developing it for a bit. You can re-run this
script as many times as you want until you're happy.

Check out the rest of the README on GitHub to wrap things up:
