Installation guide for new users How to run the kit

You’ll use the terminal to start and stop the kit.

Open the prototype folder in terminal

If you're following the installation guide, you'll already have the terminal open in the right folder.

If you're coming back to work on a prototype, you'll need to navigate to the folder:

cd ~/Documents/prototypes/juggling-licence

Or replace 'juggling-licence' with the name of your prototype.

Running the kit

In the terminal, enter:

npm start

The first time you run npm start, the kit will ask you whether you want to send anonymous data to help the team improve the service. Enter y or n to answer yes or no.

After the kit has started, you should see a message telling you that the kit is running:

Listening on port 3000 url: http://localhost:3000

Check it works

In your web browser, open http://localhost:3000 (opens in a new tab)

Screenshot of what your prototype homepage should look like.

Quitting the kit

It’s fine to leave the kit running for days or while your computer is asleep.

To quit the kit, in the terminal press the ctrl and c keys together.

The kit is now installed. Congratulations!
