Very small correction, but happy to contribute!
(or at least I think this is a typo!)
@gorsuch thanks! Every PR is appreciated.
Actually connexion is a proper spelling of the word, used mostly in British English.
@cleverdripper connexion used to be a valid spelling of the word, but it isn't fair to call it so any more; it's an obsolete spelling, being vastly outnumbered for over a hundred years and practically unused for over thirty years.

Also the ratio, connexion / connection.
