Abstract : The first cosmological results from the SuperNova Legacy Survey are presented. The recipe to obtain the deep, homogenous and complete set of 71 identified type Ia supernovae is described. The construction of the Hubble diagram is supported by precise distance measurement. The steps to obtain this distance are good differential photometry, precise calibration and light-curve modelling. All steps are detailled to present the Hubble diagram. finally the cosmological parameters are fitted from this diagram. A full error estimation (statistical and systematical) is presented.
