Resources to learn more about KDE & Manjaro

i have just started with linux a month ago, and with manjaro just today
can you plz guide me to some resources where i can learn more about these (KDE&manjaro)

i want to learn and contribute in future :blush:

Duckduckgo brings up quite a few resources.
Also your own installation - back it up with Timeshift and look at the folders in your /home.
Of course, for real contribution, some real education would also help.
