[Tex/LaTex] Title not showing

titles

I am trying to make a title page for my thesis using LaTeX, but nothing shows up. I have read other questions, but I still don't manage to get it
correct. What I have done is:

\section{\textbf{Introduction}}

\end{document}

But it doesn't show anything in my LaTeX document. I am using article document class.

Does anyone know what I should do differently?

Best Answer

Below mentioned lines are causing the issue,

\usepackage{titlesec}
\titleformat{\chapter}{\LARGE\bfseries}{\thechapter.\ }{0em}{}
\AtBeginDocument{\AtBeginShipoutNext{\AtBeginShipoutDiscard}}

By commenting these lines, title text comes in output
