Holly gives good advice.i hope to add to that. After you look at the instructions and schematics like she suggested take some time to find a blog or two for the house you have. There are good ones out there that show how to assemble and what the house should like at that stage of assembly. Also there are good you tube videos. So you can look a the pictures and watch the videos which will help you better envision the process. And ask questions here. There are a lot of people who have been in your shoes and perservered to have a house that makes them happy.
