Introduction {#sec:intro}
============

With the recent launch of CoRoT (Baglin et al. 2006), the upcoming launch of Kepler (Basri et al. 2005), and continuation of observations by ground-based teams (Bedding & Kjeldsen 2006, 2007) and MOST (Matthews et al. 2007), we stand on the threshold of a critical expansion of asteroseismology of Sun-like stars, the study of stellar interiors by observation of their global acoustic modes of oscillation. Sun-like oscillations give a very rich spectrum allowing the internal structures and dynamics to be probed down into the stellar cores to very high precision. Asteroseismic observations of many stars will allow multiple-point tests of crucial aspects of stellar evolution and dynamo theory.

The aims of the asteroFLAG collaboration are to help the community to
