Finally, time for the fun part – let's get your new application running!
Open up a new terminal window and navigate to the folder where you saved Gravity and run the following command:
npm run setup
This will download and install all the dependencies required to run Gravity using NPM (which you installed earlier).
Once installation has completed, Gravity will start the server and client and open a new browser window with the homepage, please navigate to http://localhost:3000/setup.
Use the following command to run both the server and client. Use this from now on any time you want to run your application.
npm run dev
Your browser window will open automatically and you can click on signup and create an account.
