I'm very much interested in properly learning about density functional theory calculations (DFT) in classical settings, for example as used in the theory of liquids. Apart from the success of DFT applied to many-body QM systems, for classical systems it remains the main theoretical approach of the statistical physics of liquids and solids. Similarly, but more recently, applications of fundamental measure theory (FMT, which is a more geometric approach) can be noticed more and more.
In most current liquid state theory books, these approaches are only briefly introduced and almost never at depth (as they are often assumed known by the authors). Although I have the basics of statistical mechanics, I am very new to classical DFT calculations, and would be very much interested in any piece of literature, be they review papers, lecture notes or textbooks, that would softly and slowly introduce these techniques.
