 Optionally while working in development, you can provide an implementation of the ```IJwksProvider``` interface to the constructor of the ```SmartHealthCardDecoder```. This allows you to provide a JSON Web Key Set (JKWS) containing the public key required to verify the token's signature.
 
-If not provided, the default implementation will use the Issuer's (iss) URL value found within in the scanned Smart Health Card token to make a HTTP call to obtain its matching JWKS file (public Key), to validate the token signature. Which is the desired behavior for a production system.

-In would mean that in development you would needs a public endpoint to provide the JWKS (public key).
+However, this default behavior mean a public endpoint is required to allow the JWKS (public key) to be sourced.
 
-By providing the below interface implementation (see MyJwksProvider class below) you can successfully validate signatures in development with out a public endpoint. Of course you would not do this is production.
