I am trying to add nano (sorry, I'm not a fan of Vi), but it doesn't seem to be in the default package feeds that come installed on the OpenWRT One. I did opkg update and tried to install each of the three nano packages, but without success.
Looking at opkg these are the default package feeds.

I am unsure how to work out with needs adding for the One, that contain the editor packages that I need.
