List of Glossaries not working

Hi,

I am using the template with share latex and want to add a list of glossaries before the introduction page for a master thesis.

Here is the guide: https://sv.sharelatex.com/learn/Glossaries

In demo_thesis before \begin{document} I put: \usepackage{glossaries}

\makeglossaries

\newglossaryentry{latex} { name=latex, description={Is a mark up language specially suited for scientific documents} }

\newglossaryentry{maths} { name=mathematics, description={Mathematics is what mathematicians do} }

and in liuthesis.cls I put:

\iftotalfigures {\pagestyle{plain}\listoffigures\relax\clearpage}\fi \iftotaltables {\pagestyle{plain}\listoftables\relax\clearpage}\fi \printglossaries

But when compiling there is not glossaries printed. I do not understand what I am doing wrong or how you are supposed to add list of abbreviations to the template.

Best, Olle
