It is now widely recognized that the study of the chemical properties of planet host stars provides invaluable information about the processes of planet forma- tion. In this presentation we will review some of the most recent works on this subject. We will start by looking at the results of the most prolific planet search programs concerning solar-type, FGK dwarfs. In this context we will explore how the stellar parameters relate with the planet frequency and architecture. We will then analyze the situation for their lower mass counterparts, M-dwarfs, as well as for evolved stars (giants) with planets. Overall, the presentation will highlight the importance that chemical abundances have on the formation and architecture of planetary systems.
