FErkiI am now a GURU contributor \o/
GURU is an official package repository maintained collaboratively by #Gentoo users: https://wiki.gentoo.org/wiki/Project:GURU
I maintain several unofficial packages in my overlay, like #Laminar, #Proselint, #Clight, #Vale, #OfflineIMAP3, #actionlint, #dive.
Having direct access to GURU allows me to publish these into an official source for the greater benefit of the wider #community.
