To build the project, you need to have nodejs and grunt-cli installed.
Install the nodejs packages for your operating system (and npm, if those packages do not already contain it).
Then install the grunt-cli node package globally, by running npm install -g grunt-cli.
After that run npm install in the root directory of the project.
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.
