### Description

Present status of experiment Neutrino-4 search for sterile neutrino is discussed. The effect of oscillations into sterile neutrino with parameters Δm$^2_{14}$$\approx7.3 eV^2, sin^22θ_{14}$$\approx$0.39 is observed at the 2.8σ level. The detailed analysis of possible systematic errors is presented. Plans to improve the existing installation and create a new installation with a sensitivity increased by 3 times are discussed.
