[#3539] A backport of a sentence - the parts that apply to 2.3

Hi guys!

| Q | A |
|----------------|------|
| Doc fix | no |
| New docs | no |
| Applies to | 2.3 |
| Fixed tickets | #3539 |

This backports the 2.3 parts of a paragraph that was added to 2.5 (master). I like to keep the branches different in *only* different features, so it's easy going into the future to merge things.

Thanks!
