 define Package/smartdns/description
-	smartdns server, find fastest ip.
+SmartDNS is a local DNS server which accepts DNS query requests from local network clients,
+get DNS query results from multiple upstream DNS servers concurrently, and returns the fastest IP to clients.
+Unlike dnsmasq's all-servers, smartdns returns the fastest IP.
