This resource provides a brief, readable introduction to the key concepts and practical applications of density functional theory (DFT), at a level suitable for individuals from a variety of scientific backgrounds whom have never performed DFT calculations before. It includes numerous exercises and worked examples for self study, as well as lists of references to more detailed sources for the topics covered. The text is especially well-suited for students and researchers who want to use DFT in their work, but who do not require extensive knowledge of theory and mathematical details.
