Ebook: Small Business For Dummies

What is this book supposed to be about?
It is about things you already know. He said things like you can ask money to a relative, pay your credit card debt before you start, the definition of small business and the percentage of small business in the country and what percentage are form by women, or latin or etc etc. i do not find this information helpful at all.
Blah blah, what kind of advice do you find on that?
I was expecting advice regarding the legal aspect of starting a business, forms of ownership, tax forms, etc.
The funniest part is that starts talking bad about the rest of business books, so funny.
