  We discuss the track-based alignment for the Inner Detector of the ATLAS
experiment. After describing the main alignment method based on the
minimization of hit residuals, we focus on alignment methods using information
from the electromagnetic calorimeter as well as information obtained from
physics quantities like the invariant mass of the J/$\psi$-resonance. We
present an overview of the current performance of the ATLAS Inner Detector and
conclude with some general remarks summarizing the experience of the
commissioning of the detector from the alignment point of view.
