After a passing a small roof at the beginning, traverse left on a hollow thin flake. The sound of the flake is a sign of that you are on the right track.
Thin start through the slab, then straight forward, but strenuous, climbing through the roof. At the lip of the roof there is a bolt, do not absail from this -- it is both dangerous and you will miss the true crux of the route; passing the lip.
