How to install and run i3 window manager?

[Floepje]

What i've done so far:

• *installing i3 using the package manager[libxcb-dri3-0_1]
  *trying to launch by 'exit to prompt'>typing 'i3'

Then i get the following error:
i3: Cannot open display

After some googling I can't find a similar case(puppulinux and i3). Question: What do i have to setup to make i3 running?
