Broken installation instructions for frontend: properties.json is missing

[livenson]

Followed installation instructions (npm installed et al), however after that still getting an error on start. Properties.json is missing from /static.

$ grunt serve

module.exports = function ambi (method, ...args) {
                                        ^
