To get you started you can simply clone the project
You need git to clone repository. You can get git from http://git-scm.com/.
You must have node.js and its package manager (npm) installed. You can get them from http://nodejs.org/.
You need to install global, bower, gulp and typings
$npm install -g bower
$npm install -g gulp
$npm install -g typings
Running the command npm install out of the root folder to install all development and scripting dependencies.
$npm install
Running the command bower install out of the root folder to install all app-dependencies.
$bower install
Running the command tsd install out of the root folder to install all typescript-definitions.
$typings install
after that run the gulp-script to build the application by executing
$gulp startServer
now the project lies in the build folder and is available under http://localhost:9000/
