Typo in documentation

[Stephan Eisfeld]

Hi Brian,

while reading through the new documentation parts of v1.4 I found below typo in this README.md:

When each button is connected to a single button

One button should be pin here I’d assume.

Nice new feature though! Really appreciate the addition and the way this evolved from a GitHub issue into a feature!

Cheers
Stephan
