for list of mean cli commands.

Create Your First Mean App.

To create mean app, open your command line interface and type

 $ mean init   

ex. for an example if your application name is mean-demo then just type

 $ mean init mean-demo  

this will create mean-demo folder in your workspace directory.

After creating your application go into application directory and type

 $ npm install  

that install all require dependencies in application.

After installing dependencies type $ npm start that will run your application in your browser.
