Just a quick note to say how much I appreciate the third edition. I bought the book last year and was a bit worried about getting started with 8.x and then having to learn 9. The new book is awesome – it’s clear and concise and very readable, with just enough info to be helpful without being overwhelming. As a relative newbie, I especially like the advice on setting my Mac up and your tips for the best way to do things. I’ve gotta say, that far from being put off by Blade, it makes a lot of sense to me and I can’t wait to dig in! Thanks for steering us all in the right direction…

Just skimmed the new Sage 9 book. Already picked up a dozen new tricks, for Sage or otherwise. Chock-full with best practices. Thx @retlehs 👍

Hey Ben, I just wanted to say a quick thanks for Roots / Sage & the Sage dev book I purchased. Finally found time to go through it this week and, well, I’m impressed! So yeah, thanks a bunch! :)

The book answered most of my newbie questions quite thoroughly – especially on best practises and the theory behind the folder structures etc.
