 ## Pre-release Notes
 
 **This gem was developed recently and needs real world feedback.**
 
-If you are going to use it in production environment, please note that I am still testing it. It has realistc RSpec examples that uses real X509 certificates and signed JWT to perform tests and I can say it's working great. But using it implies in security risks, you should be aware.
