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.
4. Don't have trailing spaces.
