The way of installing it, you first need a minecraft mod called MCEdit. You should probably find a tuturial on YouTube, since typing it out would be harder. I would recommend searching "How to install MCEdit for mac/pc." The mac/pc part depends on what computer you have. Once you know how to use MCEdit, use this schematic, and paste it into what ever world you want. OR, you could get Single Player commands, put this file into your schematics folder, then //load <filename> then //paste.
