Arch & Samsung Chromebook: Post-installation guide?

[stockton350]

I got the Arch linux distribution running on a USB on my Samsung Chromebook (series 3). I'd like to install a light GUI with Chromium and Totem. Can anyone point me to a guide that will help me get started now that the boot disk has been created?

I found this for the Raspberry Pi. Would it work for the Samsung
