Hello $\LaTeX$!

Here is our first full $\LaTeX$ source code that can generate a PDF file (plus a couple of comments):

% A one-line comment starts with the % sign.
\documentclass​{article}

% LaTeX packages (= libraries) should be imported here via the \usepackage{} command.

\begin{document}
Hello \LaTeX!
\end{document}

Fun question: After this program is compiled, what will the resulting PDF file contain/show?
