title: Start the development environment order: 50

You will have a new folder that has the name you picked for your pattern. If you chose test, you will have a test folder. If you chose banana, you'll have a banana folder.

If you enter that folder, you'll find a couple of subfolders:

• config holds your pattern's configuration file
• src holds your pattern's source code
• example holds the development environment

To start the development environment, enter the example folder and run: npm run start (or yarn start if you're using Yarn as a package manager.

The development environment will watch for any changes you make to the pattern's source code. When you do, it will update automatically in your browser.
