The chemical evolution of the Milky Way
  We will discuss some highlights concerning the chemical evolution of our
Galaxy, the Milky Way. First we will describe the main ingredients necessary to
build a model for the chemical evolution of the Milky Way. Then we will
illustrate some Milky Way models which includes detailed stellar
nucleosynthesis and compute the evolution of a large number of chemical
elements, including C, N, O, $\alpha$-elements, Fe and heavier. The main
observables and in particular the chemical abundances in stars and gas will be
considered. A comparison theory-observations will follow and finally some
conclusions from this astroarchaeological approach will be derived.
