 ## Introduction
 
 Proton is a project by Valve to bring gaming to the Linux desktop within their Steam client. Proton is a fork of [Wine](https://www.winehq.org/), a compatibility layer used to run Windows applications on Linux (and on other POSIX-compliant operating systems).
 
-Since Proton's conception in August of 2018, there have been 802 reviews posted to the [Proton Compatible Steam Group](https://store.steampowered.com/curator/33483305-Proton-Compatible/about/)! This is tremendous progress by Valve and the Proton community, as only 27 games were originally tested and certified at its original release date.

-Notice in the photo above that "Enable Steam Play for supported titles" shows enabled and "Enable Steam play for all other titles" is not. This means that games tested and verified to work on Proton are ready to play, but any unverified game will not run. Some unverified titles work nearly flawlessly with Proton but lack controller mappings or something relatively small. For this reason the author recommends enabling Steam play for unsupported titles and testing them out yourself!
