The lowest metallicity stars that still exist today probably carry the imprint of very few supernovae. As such, they represent a window into the early Universe. In this talk I will review the early (chemical) evolution of the Milky Way system from both modeling and observational perspectives. In particular, I will present results of the Pristine survey, a narrow-band photometric survey of the Milky Way designed to get metallicity information for millions of stars very efficiently. I will show how we can use this great discriminatory power to hunt for the very rare extremely metal-poor stars (bearers of the chemical imprint of the first stars) and to better understand the formation of the Milky Way.
