Don't expect step by step instructions for a job you'd like to do.. other books for that.
If you know how to do the work, this will make sure you do it according to code.
Many people have good ideas out there, but doesn't always comply with code.
I'd say a BIT high in price at $10, uses cheap paper and gets updated often making old version pretty much trash. A few years ago this same title only cost about $4. That's quite a price jump.
Stay up to date and safe.
