+Some of the graphs are quite complex, which is the reason why there are two versions of them: A short one mentioning only the most important things and a full version with everything I could find.
 
 In most cases I did not mention the authors of the programs/packages. This is not to diminish their effort but only for brevity (long names make things harder to read). I did not write any of the below-mentioned programs or packages. The authors are given in the documents linked in the references.
 
+\section{The Difference Between Engine, Format and Distribution}
+There are three kinds of terms that are often confused especially by new users. This will try to explain them very shortly:
+\begin{description}
+\item[engine] This is the program that does all the actual work. The original program is \TeX, a famous development is pdf\TeX, while Lua\TeX\ is the latest successor.
+\item[format] A format is a (large) collection of abbreviations (macros) that make the life easy when working with \TeX. The most commonly used formats are \LaTeX, Con\TeX t and plain\TeX. The latter one is a minimal set of macros provided by Don Knuth. Formats can be combined with different engines, exploiting the special abilities of these engines. A format is first a collection of text files, but can be compiled into a binary format that can be read in faster by the engine.
+\item[distribution] In addition to formats, a large set of suppelmentary files can be used to work with \TeX, called \emph{packages} for \LaTeX, \emph{modules} for Con\TeX t etc. To get all needed files in a convinient way, there are distributions that contain everything and are (or should be) easy to install. Examples are MiKTeX and \TeX~live.
