This is an introduction talk for Khovanov homology. Since Khovanov homology categorifies Jones polynomial, I will start with a brief discussion about Jones polynomial and the enhanced states for the bracket state sum. After that I will show how to construct Khonvanov homology from the enhanced states and its invariance under Reidemeister moves, which makes it a well defined link invariant.
