adding markdown files

[OlivierJM]

Would it be a good option to have a markdown version of the equivalent javascript file in each directory?
This would help people read everything in a clean way even on GitHub without having to clone the repo, they won't be able to use the exercises but it would help just like notes

Best way would be to have a markdown file in each directory, the markdown files will include notes and links for further reading on a specific topic.
e.g:
variables.md would include notes
variables.js this will include examples and an exercise
variables.test.js this will include tests that should pass if the user has solved the exercise.
thoughts ?
