  It is a challenge for the theoretical particle physicists to perform the
phenomenology of the Beyond Standard Model (BSM) theories using advanced
simulations which can mimic the experimental environment at the colliders as
closely as possible. In collider phenomenology jet substructure is a concept
that is used frequently to analyse the properties of the jets, characterised as
a cluster of hadrons, which is often the end result of particle collisions at
the colliders, such as Large Hadron Collider (LHC). A vast literature on jet
substructure exists both from the theory and experimental point of view. But,
even with the knowledge of Quantum Chromodynamics (QCD), it is hard to cope up
with the vastness of the applicability of the subject for a new researcher in
this field. In this review, an attempt has been made to bridge the gap between
the concept of jet substructure and its application in the collider
phenomenology. However, for detailed understanding, one should look at the
references.
