Create a prototype 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 guide to getting started 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.

Run the kit

In the terminal, enter:

npm run dev

The first time you run npm run dev, 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.

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

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.

Make your first prototype

You’ve completed the Prototype Kit set up. You’re ready to make your first prototype.
