To build the project, you need to have nodejs, grunt-cli and bower installed.
Install the nodejs packages for your operating system (and npm, if those packages do not already contain it).
Then install the grunt-cli and bower node package globally, by running npm install -g grunt-cli bower.
After that run npm install in the root directory of the project.
To download dependencies run bower install in the project directory, this downloads all reqired javascript libraries.
You are now ready to build the project by running grunt.
To start a development server on localhost, you can use grunt dev. This task will build the project, start a development server, and watch the source files for changes.
