to add this overlay to your system, use eselect-repository (recommended):

eselect repository add norayr-overlay git https://github.com/norayr/norayr-overlay.git
mkdir -p /var/db/repos/norayr-overlay
emerge --sync norayr-overlay

Alternatively, you can add it manually to /etc/portage/repos.conf directory as norayr-overlay.conf:

[norayr-overlay]
location = /var/db/repos/norayr-overlay
sync-type = git
sync-uri = https://github.com/norayr/norayr-overlay.git
priority = 50

and then sync the overlay

emaint sync -r my-overlay
