How to use systematic literature review?

Is there any documentation about the feature “systematic literature review”. At least a motivating example how to define study parameters would help.
I use JabRef 5.5

There was supposed to be, but looks like the person that implemented most of the coding refrained from writing down the documentation for the final implementation.

This is the issue tracker on github for this: Add documentation for SLR by DominikVoigt · Pull Request #333 · JabRef/user-documentation · GitHub

There has been some feedback about the feature in the forum, so maybe that will help you a little: Systematic Review Tool feedback
