Series of instructive pop-up on page, how to handle the mark up with Jquery?

I'm bulding an intranet which required pop-ups when users first use the site. What really concern me though, is how to generate the mark up into html when there are so much content to be loaded. Should i do it manually or generate the content automically ? is there good approach (pattern, method...) for either of them ? For the record, i'm a front-end developer who know a little about back-end stuff such as PHP and MySQL, hope that helps.
