ng new [app-name]command to create a new app. This will generate a basic app in the folder of the app name provided. The app has all of the features available to work with the CLI commands. Creating an app may take a few minutes to complete since npm will need to install all of the dependencies. The directory is automatically set up as a new git repository as well. If git is not your version control of choice, simply remove the .git folder and .gitignore file.
Warning: The CLI relies on some of the settings defined in the configuration files to be able to execute the commands. Take care when modifying them, particularly the package.json file.
