On section 5.1 > Describing Essential Jenkins Concepts > Stage: a stage is described as a subset, but it should either be called a "group", "set" or "superset" as a subset is the incorrect term.

I'll use an example of fruits so we have a real-world example.

A lime, an orange and a lemon are all fruits, in this case they form a set (group of objects) called fruits, but they also fall into a set called citrus. Citrus is a set made entirely of fruits,  but does not contain all fruits. So citrus is a subset of fruits, (it is a smaller group entirely contained by the group fruit).

Conversely fruits is a superset of citrus (in that it contains all objects within the citrus set, but also can contain other objects not within that set)

So in this context stages encompass a group of objects (tasks) so I'd describe it as a set of steps, but it isn't a subset of steps.

I know it's a really picky semantic difference but I wanted to ensure we had the correct wording in the materials.
