To get started with the quickstart repository, you need to grab a copy of that project by using the following command:

git clone https://github.com/angular/quickstart.git quickstart

This will copy down all the needed files from GitHub and place them in a directory called quickstart. Now, navigate into that directory:

cd quickstart

The project will have specified a bunch of libraries it is dependent on. You need to install these. That is accomplished by typing: 

npm install

Lastly, we need to serve up the application, that is, display it in a browser. That is done by typing the following command:

npm start

Worth mentioning is that this repository uses SystemJS as a module loader and for bootstrapping our Angular application.
