  This lecture provides a pedagogical instruction to the basic concepts of the
Skyrme model and its some applications. As the preliminary for understanding
the Skyrme model, we first briefly explain the large $N_c$ expansion, chiral
symmetry and its breaking. Next we give a brief review of nonlinear sigma model
including the power counting scheme of the chiral perturbation theory, starting
from the linear sigma model. We then give an exhaust explanation of the Skyrme
model and its applications. After the presentation of the Skyrme model for
baryons in free space, we introduce how to study the baryonic matter and medium
modified hadron properties by using the Skyrme model. Finally we discuss a way
to incorporate the lowest-lying vector mesons into the Skyrme model based on
the hidden local symmetry. Some possible further developments are also covered.
