How can I omit acknowledgements from the contents page?
This is what I have so far.
\section{Acknowledgements}
What do I need to add?
To illustrate Christian Hupfer's answer (and also referencing your previous question, Creating the most basic title page.), you can use the code
\documentclass[titlepage]{article}
\usepackage[utf8]{inputenc}
\usepackage{lipsum} %Just generates filler text
\title{blah blah}
\author{Blah blah}
\begin{document}
\maketitle
\tableofcontents
\section{Introduction}
\lipsum[2]%Yay filler text
\section*{Acknowledgements}
\lipsum[2]%More filler text
\end{document}
Which gives a title page, like this:
And a page with the table of contents, an introduction, and acknowledgements, like this:
Hope this helps!
\section*{Acknowledgements}
perhaps? Such a section should not be numbered anyway, so\section*
is the better variant here!
