  Recently discovered alongside its sister compounds KV$_3$Sb$_5$ and
RbV$_3$Sb$_5$, CsV$_3$Sb$_5$ crystallizes with an ideal kagome network of
vanadium and antimonene layers separated by alkali metal ions. This work
presents the electronic properties of CsV$_3$Sb$_5$, demonstrating bulk
superconductivity in single crystals with a T$_{c} = 2.5$K. The normal state
electronic structure is studied via angle-resolved photoemission spectroscopy
(ARPES) and density functional theory (DFT), which categorize CsV$_3$Sb$_5$ as
a $\mathbb{Z}_2$ topological metal. Multiple protected Dirac crossings are
predicted in close proximity to the Fermi level ($E_F$), and signatures of
normal state correlation effects are also suggested by a high temperature
charge density wave-like instability. The implications for the formation of
unconventional superconductivity in this material are discussed.
