I found this multi-part article this weekend and its just teeming with great information. I have been keeping a tab in my browser open so I can finish reading all of it, but that is getting tedious as there is just too much to do.

Mastering the viewport is the first part of the series. This tells you how you can instruct the mobile web browser on how you want your page viewed. It controls things like the zoom level the application starts at and with width it should be. The series then goes on to talk about toolkits and mobile specific css. Its a great crash course to get you started.

So I am going to post the link here for posterity, but also to share it with you.
