Read-only file system error trying to install MangoHUD
I downloaded the latest release of MangoHud and tried to install it using the "./mangohud-sh install" command, after extracting it to a subfolder within the download folder. I get a bunch of errors saying the system is read-only.
I assume I need to input some sort command to make it not read-only. Not being a Linux user I don't understand why I can't just double click a download executable to install a tiny app. Lol?

Solution
Using text files to configure things is standard practice in Linux, not too dissimilar from opening up a game's settings manually in regular PC gaming.
