The main goal of edgets overlay is to bring you the newest versions of modern software available across the internet.
Edgets is available through layman, so all you need to do is install layman (if you don't have already) and add an overlay.
# emerge --ask app-portage/layman
# layman --add edgets
More information about layman usage here.
Most of the packages are masked, so you have to unmask them or tell portage to do so.
# emerge --ask <package-name> --autounmask # type yes
# dispatch-conf # press u
More information about unmasking here.
Now, when overlay is added and package unmasked, you are ready to install it.
# emerge --ask <package-name>
See PACKAGES.md
