The LHCb experiment has measured the angle $\gamma$ of the unitarity triangle using $B\rightarrow D^{(*)}K^{(*)}$ decays and with an integrated luminosity data sample of up to $4~\rm{fb}^{-1}$ at energies in the center-of-mass of 7, 8 and $13~\rm{TeV}$. Many modes have been used, but the most recent results have been obtained with the GLW and ADS two-body decays and their extensions, the quasi-GLW and quasi-ADS modes. They are described in this paper and the results obtained by the LHCb collaboration are given. The $\gamma$ angle measurement of LHCb is the combination of many modes among which the charged $B$ decays contributed, and the most precise measurement from a single experiment.
