I posted this as answer, but it's not designed as one. I did it to have more room. :)
Belting technique should really only be attempted after a thorough understanding of the mechanics and technique of singing, and at least a baseline amount of classical technique. It takes most singers years to get to a point where they can develop their belting voice naturally and safely. Vocal health is a HUGE issue here; I can't emphasize that enough. Many pop stars have suffered from poor technique, most recently Adele, but victims abound.
I cannot tell for sure from your question, but I get the feeling (correct me if I'm wrong) that you've not taken in-person lessons before. That's fine, and you can accomplish some basic technique, including breath support, pitch control, etc. on your own. However I have to say that belting is not something you should try without a teachers assistance, in person. There's really no substitute for it. Even some teachers, teaching in person lessons have trouble explaining what must be done in a mutually understood way. When you're referring to hidden body muscles that are required to do incredibly complex things, everyone's going to describe things a different way.
If you're at all serious about learning to sing, concentrate on healthy, classical technique for awhile. (Note classical doesn't necessarily refer to classical music.) Try as hard as you can to find a good teacher you can connect with. They may be expensive, but it's cheaper than vocal surgery, and much better than ruining your voice for life. Too many people try to push their voice too hard, too early, and with too little technique. They pay a steep price for it.
