A very good introduction to getting WordPress functioning, and more importantly, installed in my mind so it actually makes sense to me.
The book started off with an introduction to WordPress, showed how to install it and set things up, and soon even walked me through making a custom "theme" from scratch that while primitive, is perfectly functional as a usable blog. If nothing else, all this helped me to understand that preconceptions aside, WordPress is not all that difficult to administer.
Starting from zero knowledge of WordPress, between the core knowledge that this book gave me, and a few quick web searches to solve specific problems I bumped into, I successfully got my very own installation of WordPress running on my OS X desktop machine. (Comes with an Apache web server as standard equipment, dont'cha know!) I wanted a sandbox to play and mess around with for a while before moving out into the real world on a real server -- normally that wouldn't be necessary if you have a webhost somewhere. This entailed such additional complexities (not covered in this book) as installing the mySQL database that WordPress relies upon (i.e. follow instructions on a web page), and activating the PHP scripting language that WordPress uses (installed in OS X, but deactivated by default). Not being a "command-line" kind of person, it was actually a fair bit easier than I'd have anticipated, but I never would have dared poke around with such things without the toehold of core WordPress knowledge that I got from this book.
There are a handful of minor English problems in the book, like there should be an "a" here, and a "the" there (and "iTune" should have an "s" at the end, spellcheck kind of stuff), but the explanations are nevertheless completely clear, so not even a full star off for that.
A second half-star off for the tendency to occasionally leap into rather frightening PHP code listings, that lack sufficient comments within the code to make them easily comprehensible to beginners. A bit more hand-holding here would have been appreciated. That said, although I've never touched PHP before, by actually taking the time to walk through the code shown (not understanding everything), I nevertheless soon had a pretty solid feel for what made things tick in WordPress. And the beginnings of the confidence that comes with actually knowing a little bit about what happens "under the hood."
...which is what I wanted this book for.
