The current book draft is 200 pages long, and the final version should be around 275. You can buy a copy of the ebook now and get free updates each time I release new chapters. The full price will be $24, but during this draft phase you can get the book at a 20% discount. (Be sure to use one of those links when you purchase; the highlighted link on the main book site has the undiscounted price.)
I hope you enjoy the tutorial!
Remember: Get a 20% discount now on the ebook and get free downloadable updates with each new chapter release.
