  This is an expository note on Fedosov's construction of deformation
quantization. Given a symplectic manifold and a connection on it, we show how
to calculate the star-product step by step.
  We draw simple diagrams to solve the recursive equations for the Fedosov
connection and for flat sections of the Weyl algebra bundle corresponding to
functions.
  We also reflect on the differences of symplectic and Riemannian geometries.
