Basically, you just have to add a time discretization to your equations. Have a look at the examples that deal with time-dependent problems [1]. E.g. step-26[2] considers the heat equation using theta-time stepping scheme and might be a good starting point. Step-35[3] uses a projection method in combination with a BDF(2) time discretization to solve for the instationary Navier-Stokes equations.
