I don't know what other software you're familiar with ... If you know a little html, you can just open a new file in Dreamweaver and starting experimenting, and use the Help tab if you get stuck. If you'd rather have instruction, a quick, cheap, and reliable way to learn basics is through your local community college, or
www.ed2go.com. You do courses online, they're inexpensive, and you'll learn everything you need to know to get started.
