Integrating PrimeNG with Angular CLI is straightforward. First, install and save the dependencies:

npm install primeng --save
npm install font-awesome --save

Second, edit the .angular-cli.json file and add three more CSS files to the styles section. These are the same files as in the SystemJS- and Webpack-based setups:

"styles": [
  "styles.css",
  "../node_modules/primeng/resources/themes/bootstrap/theme.css",
  "../node_modules/primeng/resources/primeng.min.css",
  "../node_modules/font-awesome/css/font-awesome.min.css"
]

Now, you can import desired PrimeNG modules. Refer to the Running PrimeNG with SystemJS section to see how to import PrimeNG modules. In the seed project on GitHub, we have imported the MessagesModule and put some demo code into message.component.html and message.component.ts.
