This is an example of what you can add in this text file. You can add anything you like, just like a normal HTML document. Put in links, breaking spaces, tables, ect. Don't worry about quotes or semi-colons. Just type what you want, save it, upload it, and you have your custom about us page. Erase all this info, and type in whatever you want.
Use double BR tags like below, for spacing in paragraphs.
