Overview
CoreRAD is considered stable as of the v0.3.x series and major breaking
changes will only occur if deemed necessary. CoreRAD is currently deployed and
running on several home LAN networks. Early adopters are welcome to join us in
#corerad on Gophers Slack or the
Libera.Chat IRC network.
CoreRAD is inspired by the CoreDNS and CoreDHCP projects.
