How are RK methods for solving time-dependent PDEs implemented?

I am trying to reproduce results of a thesis. It is a advection-diffusion unsteady equation. It is clearly mentioned that they have used RK method for time integration. I cannot use finite difference methods like Crank-Nicolson or any other method like that.

Thanks.
