Previous Work README section

Hello there!
I noticed that one of the gems that I maintain (Stoplight) is marked as unmaintained in the Previous Work section.
Do you mind if I move it to the Currently Active section and add a description there?

Sure! The purpose of that section is to help people choose what solution is best for them. It should be concise, and focus on how stoplight compares to faulty.
