I highly recommend it too. The advice and method concrete enough but not too specific. It tells you a bit what to do, why and how. Since it's iterate process its gets better by time and goes well with agile development.
At first your goal is to define your assumptions, test them with potential customers and gather facts. Next integrate the facts into your product development. Continue verifying your product and business with customers, start your sales and go-to-market activities. Last, if you're successful, scale your company.
