 is a public key credential source whose credential private key is stored in the authenticator,
 client or client device. Such client-side storage requires a resident credential capable authenticator.
 This is only supported by FIDO2 hardware, not by older U2F hardware.
-On the browser side, at the moment only Microsoft Edge 18 seems to be supporting it.
 
 ### How does it work?
 With normal **server-side key** process, the user enters its username (and maybe password),
 then the server replys with a list of all public key credential identifier, which had been registered by the user.
 Then, the authenticator takes the first of the provided credential identifier, which has been issued by himself,
 and responses with a signature which can be validated with the public key provided on registration.
-With **client-side key** process, the user don't have to provide it's username or password, he can actually just press a 'login' button!
-Then, the server don't send any identifier; rather, the authenticator is looking up in it's own memory,
+With **client-side key** process, the user don't have to provide an username or password.
+The server don't send any identifier; rather, the authenticator is looking up in it's own memory,
 if there is a key saved for this relying party. If yes, he's responding the same way like he's doing if you provide a
 list of identifier, there is no difference in checking the registration.
+Resident Credential is supported by Windows 10 (Firefox, Chromium). Browser on old OS like Windows 7
+do a fallback to FIDO U2F, which doesn't support resident credential.
 
 ### How can I use it with this library?
