Install MEAN
To start as a MEAN first install mean-cli package as globally from npm repository
$ npm install -g mean-cli
if you are using OSX, *nix, BSD then you can install mean-cli with sudo syntex
ex.
$ sudo npm install -g mean-cli
after installing mean-cli type

$ mean
OR
$mean –help
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.
