Hole-doped cuprates have a very rich phase diagram as a function of doping. This is due to a charge inhomogeneity in CuO_2 planes: the charge distribution in CuO_2 planes is inhomogeneous both on a nanoscale and macroscale. Depending on doping level, the CuO_2 planes comprise at least four different types of clusters having a size of a few nanometers. Each type of clusters has its own features. As a consequence, the common phase diagram consists of, at least, seven different energy/temperature scales. As an example, we consider a phase diagram of Bi2212.5 pages, 4 figuresSuperconductivityStrongly Correlated Electronstext
