Derivative size for responsive images

In the announcement of Grav 0.9.43, we can read:

Also Responsive Images have been improved to support configurable derivative sizes.

Is there documentation about this new feature?

Yup -> Sizes with media queries

BTW markdown format is not working in latest release but is working in Develop branch. Twig version works in current release though.

Thanks a lot. For the record, the three arguments for derivatives are min width, max width and step, so if we put 1000, 3000, 1000, Grav will create images for 1000w, 2000w and 3000w.

Feel free to edit the documentation (via the github link) if you feel like this information would be helpful to others. Thanks!
