 # KrakenD api gateway playground
 
-Poszczególne etapy pracy i poznawania krakend w osobnych brancz'ach.
+## etap2 (JWT)
 
-Całość oparta do docker.
+Tutaj już będzie deko więcej roboty. Backend z etapu1, czyli prosty nie zabezpieczony serwer REST.
+
+Do naszej infrastruktury dodajemy usługę [Hydra](https://www.ory.sh/hydra/docs/), która jest dostawcą protokołu **OAuth2** oraz **OpenID** aby zabezpieczyć nasze api za pomocą [JWT](https://jwt.io/).
+
+W poprzednim przykładzie (etap1) KrakenD posłóżył nam do sekwencji zapytań do api i jednej odpowiedzi
+W tym etapie wprowadzimy nowy request zabezpieczony tokenem JWT:
+
