 In the previous chapters we have only seen very short \LaTeX{} examples. \LaTeX{} can of course also be used to create larger documents and projects, such as a thesis. 
 In order not to lose the overview in the source code and to avoid that source files become too long, a reasonable structuring of a larger \LaTeX{} project is advisable. For this purpose, the source code is divided into different files, which will be discussed in more detail in the following sections.
