AngstromFeeds
A 'feed' is a place where you can download additional software for the Angstrom distribution. You can browse the available packages for Angstrom through a nice web interface:
The feeds are organized by categories, allowing to quickly find the software you need. By clicking on a package name, you can view a brief description and the lists of dependencies. But don't worry about dependencies because the Angstrom package manager will automatically install the required packages for any software you will install.

Configuring feeds
You can configure additional feeds. A nice howto is this one The beforementioned link is unresponsive. I found an easy way is to cd into /etc/opkg. There you will see lots of files with -feed.conf. Edit the file called base-feed.conf. I changed src/gz base http://www.angstrom-distribution.org/feeds/2008/ipk/glibc/armv7a/base to src/gz base http://www.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv7a/base. You can also make a new file with the latter in it and comment out the first.
