ReadMe says both does return new collection and does not

[selner]

Was taking a look at this project to see if i wanted to use it and noticed a small inconsistency in the readme.

These two items appear to contradict themselves about whether or not they return a new Collection:

• random() Shuffle and return a new Collection. ❎
• unique() Deduplicate the collection and return a new Collection. ❎

The text description says they do return a new Collection but the icon states that they do not.

Clearly not a critical issue but thought you'd want to know.
