Many real-life applications support temporal services. Stack Overflow supports all of the features listed in the overview. In this section, we'll use Factorio School as a running example.

Liftwizard and Factorio School were both created by the same author and Factorio School leverages Liftwizard's temporal support. In the next section, we'll create and edit a blueprint, and see how non-destructive edits work.
