 In chapter~\ref{ch:architecture} we provide an overview over the \appname 's internal architecture while chapter~\ref{ch:ui} presents and explains the graphical user interface.
 To provide an overview of what is going on, chapter~\ref{ch:progress} lists features and their degree of completion.
+A glossary of some of the more difficult terms we can be found in the appendix (table~\ref{table:glossary}).
 
 \appname\ is currently a work in progress so keep in mind that any of the here presented screenshot, diagram or other information may be slightly outdated\footnote{even this one}.
 Also note that some PDF viewers have problems with vector graphics exported from Visual Paradigm, so if you feel like there is a missing line in a class or component diagram, you are wrong.
