  We present preliminary results of the high resolution $ (0.10^{\prime\prime}
\times 0.15^{\prime\prime}) $ observations of the high mass star forming region
S255IR with ALMA in several spectral windows from ~ 335 GHz to ~ 350 GHz. The
main target lines were C$^{34}$S(7-6), CH$_3$CN($19_K-18_K$), CO(3-2) and
SiO(8-7), however many other lines of various molecules have been detected,
too. We present sample spectra and maps, discuss briefly the source structure
and kinematics. A new, never predicted methanol maser line has been discovered.
