is not Wikipedia, which means that a definition page should generally start with a precise and rigorous definition, without introduction. In some cases, especially when the defined concept would otherwise be hard to grasp, the rigorous definition can be preceded by an informal one. The informal definition is placed in section named Informal Definition.
