2. Run it locally
The site open in your browser, with your own account on it — about 10 minutes.
"Locally" means on your own computer, visible only to you. Nothing is on the internet yet. You can break anything here without consequence.
Say this
Set this project up to run locally: install the dependencies, create the local database, and start the dev server. Then tell me the address to open in my browser.
The site opens at http://localhost:3000.
Create the first account
Sign up on your own running copy. The first account you register becomes the administrator — that is you.
Done when
The site loads, you have signed up, and you are looking at a logged-in page.
The dev server has to keep running
The site is only up while that terminal window is open. Closing it stops the site; running the command again brings it back. Nothing is lost either way.
