Every example has to be in its own folder. The name of the folder should
tell the reader what the example shows.
Contents of that folder:
Every example has to have a Makefile which contains all the commands
necessary to compile the document.
The main TeX file should have the same name as the folder.
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.
