Provide detailed documentation

[BioPhoton]

I tested it and realized that there is (besides a very general intro) no helpful documentation provided.

Neither --help nor the readme explains what the suggestions mean exactly.
Also, no tests are there. So I have no way to figure out the exact meaning of the suggestions.

I guess this is because of a very early stage of this repo.

Anyway, GREAT work!!!

Thanks for your effort,
Michael
