16. Learn i3 from scratch

17. Install & try i3
- pacman, apt, yum, etc

session as “i3” and done!
- if you prefer startx like me, modify ~/.xinitrc
to use i3

Make sure you have the ability to edit
~/.i3/config, otherwise you gonna be stucked
cause the default i3 setting might not always
work for you
