In 2001 a set of PHP scripts were let loose on the open Internet. Those scripts, which took user-generated data and used it to dynamically create html pages, contained the ideas and the algorithms that are the core of today’s Nucleus CMS. Though Nucleus CMS 3.2 is far more flexible and powerful than the scripts from which it emerged, it still expresses the values that guided its birth: flexibility, security, and computational elegance.
