2 6 FOREWORD CO 5 BOLD (COnservative COde for the COmputation of COmpressible COnvection in a BOx of L Dimensions, L=2,3) is a radiation hydrodynamics code designed for modelling the convective layers and atmospheres of stars. The atmosphere of a star requires a complex modelling since the dynamics and state of the stellar gas are tightly coupled to the electromagnetic radiation. This involves a realistic equation of state including ionisation and formation and dissociation of molecules. After 6 years from the first CO 5 BOLD workshop, that took place in Freiburg, Germany, it was time to gather developers and users of CO 5 BOLD again, and to provide a forum to present and discuss results obtained with the code. It was also a good opportunity to celebrate the 50th birthday of Hans-Günter Ludwig, one of the developer of CO 5 BOLD code and a very active member of the CO 5 BOLD community. These proceedings record the results that have been presented at the workshop. At the third CO 5 BOLD workshop, they will allow to easily track the improvements of the CO 5 BOLD code, its related spectral synthesis, and the progress in the physical description achieved by the CO 5 BOLD models.
