Exact results for the AdS3/CFT2 correspondence

The AdS3/CFT2 correspondence is an intriguing instance of holography. Despite its long and rich history, only recently we have developed the techniques to obtain exact results for generic (non-protected) observables at generic points of the parameter space. In this talk I will overview this progress, describe the major stumbling blocks and how they have been overcome, and outline the remaining challenges for the field.
