I will describe the methodology of obtaining knot invariants from Chern Simons field theory after reviewing well-known knot polynomials. One of the challenging open problem is the classification of knots. To check the power of Chern-Simons field theoretic invariants, we investigate mutant knot pairs which are indistinguishable by well-known polynomials. Finally, I will review the developments providing justification for integer coefficients of 
the Laurent form of knot polynomials.
