Adding this overlay with layman

To add my overlay:

cd /etc/layman/overlays

wget https://raw.githubusercontent.com/chaoskagami/chaos-overlay/master/metadata/chaos.xml

layman -a chaos

layman -S

Of course, if you don't have wget (why?) you can also use curl. Or aria2. Or whatever. And if you don't use layman - good luck, have fun with managing manual syncs.

As a note - my repo has the masters = gentoo in the config, so my repo won't annoy you like others every emerge. It also won't cause eix to explode.

Don't ever use unstable. That branch is for when I add a new ebuild, and need to test changes rapidly before merging to master. In other words, unstable is guaranteed to to break, never mind maybe.
