The Carnegie Supernova Project (CSP) was a five-year observational
survey conducted at the Las Campanas Observatory that obtained
high-quality light curves and spectroscopy of 300 supernovae.
I will present an overview of the CSP and results so far obtained.
In doing so I will review the hierarchy of supernovae, and place
in context our current understanding of exploding stars and
their use as cosmological distance indicators.
