+DNS configuration
+=================
+
+This folder contains configuration for our DNS zones. The zones are hosted with
+Google Cloud DNS, which supports zone-file based import/export.
+
+Currently there is no automation to deploy these zones, but CI will check their
+integrity.
+
+*Note: While each zone file specifies an SOA record, it only exists to satisfy
+`named-checkzone`. Cloud DNS manages this record for us.*
