The plans will include drawings, dimensions, individual part breakdowns, and enough general information that anyone who can weld and follow directions will be able to build it. The plans do a great job of laying out each piece with dimensions and then show you how to build each sub-assembly and finally how to put everything together. Yes, it shows where hinges, shelves, the charcoal chute and insulation goes as well.
Best part is many of the folks on this site have built one so getting "real experience" help and information is only a post away.
Good luck with whatever you decide to build. Must be a pretty cool feeling to bring a type of cooking into an area that has not experienced it before. I can only imagine you are going to be pretty popular in the near future!
