The title, author, and date of your document are information that
various LaTeX commands can make use of, if you provide it. It
is a good habit to get into to provide this information in the
preamble of your document. (Remember that the preamble refers to any
commands between the \documentclass command and the
\begin{document} command.) The commands are:
\title{yourtitlehere}
\author{yournamehere}
\date{currentdate}
Given that you have provided this information in the preamble, you may
or may not want a title heading. If you do, place a \maketitle
command immediately after the \begin{document} command.
Practice: Create a document of three pages with a title
heading, using the \pagestyle{plain} command.
