What do I have to type here to have "Welcome to my Site" display?

You've got most of the answer in your question. The title, "document.write", is the name of the function to call; and "Welcome to my Site" is the argument you will pass in parentheses after the function name. A semicolon afterwards is optional, but good practice:
document.write("Welcome to my site");
