 ## Usage
 The library is designed to be fairly straightforward and easy to use.

+### Generating Google Authenticator URIs
+One can easily generate configurations for Google Authenticator, by using `GenerateGoogleAuthenticator()` static method

+These methods return configuration objects, that can then be plugged into `OtpGenerator` constructor, or just returned
