Share 'How Does This Work'

I'm not sure how this all works so I'll need a little guidance. First let me introduce myself, I'm Frederick (Rick) Coxen and a first time author.  My book "The Great Promise" is my first book and I'm self-publishing.  I've joined "Book Blogs" to share my story, and for those that are interested, an opportunity to review my manuscript prior to printing.  So, how do I proceed from here?
