  I review the general aspects of cosmological parameter estimation from
observations of the cosmic microwave background (CMB) temperature anisotropies
in the framework of inflationary adiabatic models. The most recent CMB datasets
are starting to give good constraints on the relevant parameters of
inflationary adiabatic models. They point toward a model consistent with the
basic predictions of inflation: a nearly flat universe, with a nearly scale
invariant spectrum of primordial fluctuation.
