Hello there, how's everything?
Before I get on with my issue I just wanna say thanks for the work you've done with this program, I've used it on windows for a while now and I've had a lot of fun with it. However, now that I've acquired a steam deck, I would like to use your program again. Being a lifetime user of windows though, I quite literally can't even begin to understand the set up instructions. I looked for a video guide on youtube, to no avail. I reckon it still will be some time before RemotePlayWhatever is as easy to install as any Decky plugin, so I ask, could you please make a step by step video guide on how to set it up on Linux and get it to work on gaming mode?
