The purpose of this report is to demonstrate the search for integrability conditions by the normal form method. We have chosen an equation of the Lienard-type as the object of the demonstration. We presented the equation as a dynamical system and parameterized it. We constructed polynomial equations in the system parameters which should be satisfied for the integrable cases.
