-### GeoLite2 database
+### Geolocation databases
 
 For geolocation to work you need a MaxMind format database, for full functionality you need the GeoLite2-ASN and GeoLite2-City databses. Unfortunately you have to sign up with [MaxMind](https://maxmind.com) to obtain them. Once you have a license key there is a helper script in [contrib/maxmind-download.sh](contrib/maxmind-download.sh) that helps you with keeping the databse updated.
 
+As an alternative to MaxMind there is also [DB-IP who offer their free databases without a login](https://db-ip.com/db/lite.php). You want the City and ASN databases in mmdb format.
+
+**Don't forget to set the atttribution in the template configuration appropriately.**
+
+See the file `templates/extra.toml`.
+
 Since v1.0 echoip-slatecave reloads the databses when it rececieves a `USR1` signal.
