Understanding the nature of the first stars is a major challenge of modern cosmology. Despite their importance for the formation of subsequent stars and galaxies, their mass distribution is still uncertain due to a lack of direct observations. Extremely metal-poor stars in the Milky Way allow to constrain the mass of their progenitor supernovae and thereby provide precious information about the first generation of stars. I will give a general introduction to stellar archaeology, the main open questions, and discuss several of our recent results. In particular, I will present a novel scenario for the formation of so-called carbon-enhanced metal-poor stars as a consequence on inhomogeneous metal mixing.
