There's things you need to understand that will make everything else much quicker and easier. I will try my best to cover all of those.
You need a text editor with color syntax highlighting. Here's a free one:
right-click on your desktop, select "New Folder", name the folder "root". That's your root folder for now.
Web URL's look like "http://www.panamaquono.com/tutorials/" In this URL the www.panamaquono.com part represents the root folder of your website, and the /tutorials/ part represents a subfolder within the root directory of your site.
Web browsers will display the folder structure of your root directory but also the filename of anything within the directory that you navigate to, along with its file extension. Like this: "http://www.panamaquono.com/tutorials/tutorials.pdf"
There's one case though in which the web browser will not display the name of the file...
Web browsers are trained to look for an index page. Navigate into the root folder you just made and create a new file, name it "index.html"
You're now on your way to having a website, Good Job!
If you've designed a website in Illustrator or Photoshop that you'd like to see online.
If all went well when you go back to Safari and refresh your page you'll see your design.
