+The package formats datasets containing information about a system's lattice parameters electron density, and 
+electrostatic potentials. ``MacroDensity`` contains some high-level tools and functions to calculate
+the planar and macroscopic average (as defined in Jackson's Electrodynamics [@Jackson:1999]), the spherical average 
+around a user-defined point, and calculates band energy offsets, deformation potential, and volume changes of a system. 
+``MacroDensity`` can also calculate the localised potential around a certain atomic nucleus of a system. The approach
+to calculating this on site (Hartree) potential is similar to calculating the Madelung potential. this is useful for 
+electron energy level predictions [@aron:2014].
