## Structure

1. Every example has to be in its own folder. The name of the folder should
   tell the reader what the example shows.
2. Contents of that folder:
    1. Every example has to have a `Makefile` which contains all the commands
       necessary to compile the document.
    2. The main TeX file should have the same name as the folder.
    3. Every example has to have a `README.md`. For images / graphic examples,
       this should include the rendered image. For documents, there should be
       some example text explaining what it is about.
3. Use spaces for indenting.
