The simple answer is, a file named "index.XXXX" will show up automatically when you type your URL. XXXX in this instance is either "php", "htm", or "html". So, create a file of your choice with the proper name, and it will show up automatically. So when you type http://256mayas.x10.mx/ it will really mean http://256mayas.x10.mx/index.html for example. This file must be placed in your public_html folder.
