Trying to add contenful to existing site that uses gulp

Hey everyone. I’m looking to add contentful to an existing site - which seems really straightforward and simple, but the problem is, the existing site is a bootstrap theme that uses gulp, which I’ve never worked with.

Could someone explain to me how I might go about this? I’ve watched a couple videos on gulp, but that hasn’t really helped. I can’t seem to figure out how to get up and running.
