installing GuixSD on a Macbook Air A1304

[Quiliro]

I have received an old Macbook Air (A1304 from 2009). This machine has
a USB port. So, I could connect a USB WiFi dongle in replacement for
the non-free embedded WiFi device. Also, the nVidia GeForce 9400m video
card is reported on h-node.org to not work. But I have used it with
Parabola live and it is type NV50 which is perfectly supported by
Nouveau.

I would like to:
- view videos online. Not typing long URLs. Maybe copy and paste. But I
think that is too long considering that clicking is just one step.
- read and write text
- write spreadsheets
- listen to podcasts
- read email

I understand I could do all this with i3 window manager and emacs.

Would someone guide me how to install and configure GuixSD for this
UEFI machine? Thanks
