Done f'ed up and order an all extract.....and I never done one...

From norther brewer I ordered an Orange Wit and I got it in the mail yesterday and opened it and realized it was all extract. Like two bottles of malt extract. I've done mini-mash and all grain but never this. All it says is to boil two gallons of water and then throw the extract and hops in, cool it, add more water to 5gal. I got yeast so that doesn't matter. Is that all it really is. I mean this is gonna take like an hour and a half...

figured I ask this stupid question here...
