There is a typo in that line, should say EXAMPLE TO CONFIGURE GPIO AS INPUT

That was a great catch on the comment error/typo. Espressif are fine with us creating pull requests (assuming we have basic Github skills) to make the changes our-selves. I wanted the practice so made the change and issued a pull-request.

Thanks nkolban. Yes, pull requests to fix issues (from typos on up) are welcome!
