I’ve just finished writing up some more documentation, to help everyone who’s learning how to use jQuery. I’d like to thank Bruno for helping me sort out all the Prototype/jQuery weirdness and Derek for looking at the selector differences.

• jQuery Base Module. I wrote up how exactly the $() function works and broke up the documentation for all the individual function-types into separate pages.
• jQuery Selectors. One of the most important parts of jQuery is its ability to quickly select different HTML elements. This page shows how this works and how CSS and XPath can play nicely together.
• Using CSS with jQuery. This page details the similarities and differences between the CSS 1-3 specifications and how they’re implemented in jQuery.
• Using XPath with jQuery. An explanation of what basic aspects of XPath are supported, on top of CSS.
• Custom Selectors. A number of custom selectors were introduced, that weren’t readily available in either CSS or XPath.
• Using Prototype and jQuery. Finally, detailed documentation on how jQuery works when used with Prototype, what to be careful of, and what to look out for.

My next big step with jQuery is to tune up some of the code, for speed and clarity, (thanks Tim!), write a couple new plugins, and create the new plugin repository for developers to use. All of these should be coming out within the next couple days/weeks.
