Query: Dark atoms and composite dark matter   I selectively review the theoretical properties and observational limits
pertaining to dark atoms, as well as composite dark matter candidates bound by
a confining gauge interaction: dark glueballs, glueballinos, mesons and
baryons. Emphasis is given to cosmological, direct and indirect detection
constraints.
