You missed the entire point of the post..the author is arguing docs in md are the src...

But we already have a folder for docs? It's called "docs". If the docs are the source code, that's fine, but that doesn't mean we have to move them into the source code folder. We already have somewhere to put them! The end goal should be for the source code folder to be in the .gitignore, same as you would with object files... but if the docs are in there, now you're stuck.
