We review the long term project of the ALPHA collaboration to compute in QCD\nthe running coupling constant and quark masses at high energy scales in terms\nof low energy hadronic quantities. The adapted techniques required to\nnumerically carry out the required multiscale non-perturbative calculation with\nour special emphasis on the control of systematic errors are summarized. The\ncomplete results in the two dynamical flavor approximation are reviewed and an\noutlook is given on the ongoing three flavor extension of the programme with\nimproved target precision.\n
