 The case study, simulated with the Particle in Cell (PIC) code Smilei, is a set-up of laser-plasma acceleration with external injection of a relativistic electron bunch. At first, only the propagation of an intense laser pulse in vacuum is simulated. Afterwards, the plasma is added, to study the generation of plasma waves. Finally, a relativistic electron bunch is added and injected in the plasma wave, to be accelerated.
 
-The exercises introduce the physics of the considered set-up, teach some sanity checks to compare the code results with theory and introduce the basic postprocessing of interest for PIC simulations of plasma acceleration. 
+The exercises introduce the physics of the considered set-up, teach how to compare the code results with analytical theory when possible and introduce the basic postprocessing of interest for PIC simulations of plasma acceleration.

+Following is an animation of the first laser wakefield acceleration case study of the practical.
 The laser pulse (envelope of the electric field depicted in red) excites a relativistic plasma wave, whose electronic density is shown with a blue-white volume rendering.
 The white particles represent the relativistic electron bunch that is injected and accelerated in the plasma wave.
