I use an unnumbered chapter for my abstract, followed by the table of contents. However, that unnumbered chapter does not appear in the ToC. How can I fix this?
\documentclass[12pt,a4paper, oneside, bold]{thesis}
\usepackage[left=3cm,right=2cm,top=3cm,bottom=2cm]{geometry}
\begin{document}
\chapter*{abstract}
\tableofcontents
\chapter{1}
\chapter{2}
\chapter{3}
\end{document}
