  In this publication the first official release of the JEWEL 2.0.0 code is
presented. JEWEL is a Monte Carlo event generator simulating QCD jet evolution
in heavy-ion collisions. It treats the interplay of QCD radiation and
re-scattering in a medium with fully microscopic dynamics in a consistent
perturbative framework with minimal assumptions. After a qualitative
introduction into the physics of JEWEL detailed information about the practical
aspects of using the code is given.
