^ Emphasis on the second to last sentence from HoF. One of us still needs to step up and write a comprehensive guide (but a newer, much different version of Mysidia has been in development for a while).
This post I made covers some interesting stuff, coding-wise, in regards to this framework.
As for learning - yeah, codecademy is great start. Of the books I recommended,
THIS ONE is definitely one I'd recommend the most for Javascript, especially for someone who is a more visual learner. Also from the same list before,
the pocket manual for jQuery. It's like having the official website in your palm. It's very well formatted and kind of fun just to skim through to learn. These two books I recommend a ton.
PHP is a little harder to pick up on. There are a lot of little differences between it and Javascript at the core, but it's usually nothing a google search or two won't fix.
StackOverflow is a godsend.
