  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.
