Port KDE System Administration to Develop or elsewhere
Currently we have two important pages in Userbase about System Administration:
https://userbase.kde.org/KDE_System_Administration/Environment_Variables
https://userbase.kde.org/KDE_System_Administration/Configuration_Files
Neither should be important to users, so they shouldn't be in Userbase to begin with.
Environment variables are useful for developers, but I'm not sure it should necessarily go to Develop. This information could go to the Plasma, KScreen, KWin repos or even simply the Community wiki.
Configuration Files is strongly related to Kiosk, it should be possible to merge it there.
