+
+# Purpose
+
+Very fast and declarative config DNS with built in adblocking. Used for local domain name configuration as well.
+
+# Notes
+
+Deployments in cluster, on RaspberryPis, and the PiBox. Cluster and Tailscale use the cluster endpoint, clients use the RaspberyPis, and home network used the PiBox.
+
+DNS over TLS to Cloudflare servers and somewhat agressive blocking.
