The previous question Hidden markdown text on GitHub covers how to hide text using comments for the purposes of notes to self.
I have done this, but people can still click through to the code of README.md and see the hidden comments. Is there a way of keeping the source code of README.md private?
A search for any way to do this returns information about hiding things using comments. I'm fine with that, but I would like a way to keep the code itself private.
