+About this Project
+------------------
+
+This is an extremely simple DNS seeder that ensures the Monero DNS seed A records are
+fully populated. It's written in php-cli, and it's a little hacky in parts. It works
+with Gandi's API only, which means there is no requirement for running your own BIND
+server. Feel free to port this to python if you don't like semi-hacky php-cli code.
+
+Monero DNS seeds are live at:
