Determination of high precision abundances is an important goal of all spectroscopic studies. Accurate modelling of stellar spectra is therefore essential to determine these abundances and stellar parameters. I will explain in this talk the non-Local Thermodynamic Equilibrium (non-LTE) approach to modelling stellar spectra of cool stars, highlighting the important role that Hydrogen collisions play.
