When you download and unzip the file, inside you'll find a folder called "files" and a file called "START HERE". Double click the Start Here file, which will open it in your browser. (If not, Right Click on file, go to "Open With", and choose "Internet Explorer", or whatever browser you have. If no browsers are displayed, go to Choose Program, and select a program called "Internet Explorer" or "Netscape Navigator" )
When "START HERE" opens, click on the "web tao" logo at the top, which will take you to the HTML guide. I created this so you didn't have to go into the "files" folder, and fish for an Index file.
