I dont know of a guide off the top of my head that specifically uses bannerbomb, and since you didnt say what version you're on i'm gonna assume it's not 4.0 since you'd have to use bannerbomb.
But use bannerbomb + hackmii. That will get you the home brew channel installed. You can just follow the direction on those two sites. Once you get the home brew channel installed you can follow any guide that says TWP. The TWP is just the medium the guide is going to get HBC (Home brew channel) installed.
Here's a more comprehensive guide to using bannerbomb + installing HBC.
