Jets and Jet Algorithms

There is no jet substructure without jets. Jets are ubiquitous objects in collider physics, which have been used for 40 years. This Chapter discusses the concept jets as collimated sprays of particles (or flows of energy). It also introduces the algorithms which are used for their practical definitions, basic experimental aspects and the software implementation.
