Am I missing something??

In this post about reshade.. modemworld.me/2015/08/11/reshade-post-pr...d-life-in-real-time/
there is some kind of app.. however, in the most recent reshade release, I do not see anything called, ReShade Mediator
so, now i am all panicked thinking i messed it up, lol.
is there a way to get access to a stand alone .... editor?

That post is outdated. ReShade 3.0 has a realtime in-game GUI for configuration. There is no external app anymore. You use the downloaded setup tool to select a game and that’s it, everything ready and set up, none of the complicated installation process from before.
