With great (relief? fanfare?) enthusiasm, I am happy to announce the availability of the Liferay Portal Administrator's Guide, Third Edition. Now coming in at a more hefty 313 pages, this is the best Admin Guide that we have ever released. It's been updated to cover Liferay 5.2.x, which means coverage of the Liferay Control Panel. It also includes a new chapter on Liferay's collaboration suite, in addition to hundreds of other improvements, including an expanded performance tuning section.

Thanks are due not only to the many Liferay-ers who helped me out with technical details (your names are listed in the front of the book), but also to the many members of the Liferay community who have been so good with feedback and wiki articles. Seriously, the book would not be nearly as complete as it is without you. I think we are doing amazing things together and providing a great piece of software that can serve everybody from the largest corporation to the smallest non-profit.

You can go to our documentation page here to get it.
