+## What is it ?
+For the uninitiated, JSON Web Token(JWT) is a JSON based standard (<a href="https://tools.ietf.org/html/rfc7519">RFC-7519</a>) for creating assertions or access tokens that consists of some claims (encoded within the assertion).
+This assertion can be used in some kind of bearer authentication mechanism that the server will provide to clients, and the clients can make use of the provided assertion for accessing resources.
+
+Few good resources on this material which I found useful are:
