So I've noticed that lunar doesn't seem to mention the cli install anywhere on the website. And I'm kind of wondering why? Copying and pasting one command is SO much easier then manually going to the website, downloading the file, opening the file, spamming next on all the tos agreements, finding and opening the shortcut on your desktop etc etc..
The PowerShell Install: winget install Moonsworth.LunarClient; cd ~\AppData\Local\Programs\launcher\; & '.\Lunar Client.exe'
(PS: the command auto downloads the latest version so needing to worry about manually updating it is not a concern)
