AGB stars are the source for the main component of the s-process. Here we discuss both the properties which are reasonably well known and those which still suffer from substantial uncertainties. In the former case, we are fairly sure that the s-process contribution from AGB stars comes from masses between about 1 and 3 M-circle dot, and the dominant neutron source is the C-13(alpha,n)O-16 reaction. In the latter category remains the formation mechanism for the C-13-pocket. Attempts at including rotation seem to inhibit neutron capture reactions. Explaining the observations seems to require a spread in the size of the C-13-pocket so some stochastic process, such as rotation, must be involved.
