Documentation or how to use with angular

I am trying to use this with my angular project and unfortunately, there is no documentation or how to? for that. Also, I prefer using this because working with a Metronic template and they've used this.

So, first of all, it'd be great if someone can assist on how to use gmaps with an angular (angular2 or 4 or 5) application. Basically, I just want to get the map data of a selected place. Initially the latitude and the longitude.
