under Shape Constraints in Diminishing Returns

It should read:
Diminishing returns means that the marginal gain of increasing a certain feature value will decrease as we increase the value.

Not this:
Diminishing returns means that the marginal gain of increasing certain a feature value will decrease as we increase the value.

It's not a big deal but i was really confused for a minute trying to understand what it meant.
Also is there a better place to bring up minor things like this?
