 To register a new user passkey, use the `passageFlex.passkey.register` method.
 
+This is a three step process:
+1. Your app should POST a user identifier (like an email) to your backend, which should request a transaction id from the Passage server to return to your app.
+2. Your app should then call `passageFlex.passkey.register(transactionId)` to prompt your user to create a passkey. On success, the `register` method will return a nonce.
