We study D-branes on the quintic CY by combining results from several direc
tions: general results on holomorphic curves and vector bundles, stringy ge
ometry and mirror symmetry, and the boundary states in Gepner models recent
ly constructed by Recknagel and Schomerus, to begin sketching a picture of
D-branes in the stringy regime. We also make first steps towards computing
superpotentials on the D-brane world-volumes.
