Jen's book, Joomla! Start to Finish: How to Plan, Execute, and Maintain Your Website is available at booksellers everywhere
The book starts with two chapters of how to plan your Joomla website. While Jen focuses on Joomla, these tips can be used for planning any website. If the site is well-planned, the site will be executed more quickly, since there are no lingering questions about what the client really wanted, or unhappy surprises when the client sees what was built for them.
Jen goes on to describe Joomla's installation, the SCAM (sections, categories, articles, and menus), putting together a home page, and custom templating. She wraps up with important points about maintaining the site going forward, including hosting and upgrades.
"Joomla! Start to Finish will be dog-eared, and worn by the time you are done! It is a well written and highly useful volume for any Joomla! developer or web site administrator. If you only buy one Joomla! book - buy this one"
