  The recently discovered layered kagome superconductors
$\textit{A}$V$_{3}$Sb$_{5}$ ($\textit{A}$ = K, Rb, Cs) have garnered
significant attention, as they exhibit an intriguing combination of
superconductivity, charge density wave (CDW) order, and nontrivial band
topology. As such, these kagome systems serve as an exceptional quantum
platform for investigating the intricate interplay between electron correlation
effects, geometric frustration, and topological electronic structure. A
comprehensive understanding of the underlying electronic structure is crucial
for unveiling the nature and origin of the CDW order, as well as determining
the electron pairing symmetry in the kagome superconductors. In this review, we
present a concise survey of the electronic properties of
$\textit{A}$V$_{3}$Sb$_{5}$, with a particular focus on the insights derived
from angle-resolved photoemission spectroscopy (ARPES). Through the lens of
ARPES, we shed light on the electronic characteristics of the kagome
superconductors $\textit{A}$V$_{3}$Sb$_{5}$, which will pave the way for
exciting new research frontiers in kagome-related physics.
