generate Corefile which uses your ISP's DNS servers to resolve domain names in China and uses OpenDNS/Cloudflare/Google DNS servers to resolve domain names outside China for CoreDNS. You should change 119.29.29.29/223.5.5.5 to your ISP's DNS server address or use public DNS server such as 114/DNSPod etc. directly.

#!/bin/sh
echo 'use "curl -sSL git.io/corefile | bash" to update Corefile'
echo "remember to change 192.168.1.1 to your ISP's DNS server address or use public DNS server such as 114/DNSPod etc. directly"

coredns 把proxy插件给干掉了，增加进去编译不成功了，有替代的插件吗？

参考：
https://github.com/missdeer/coredns_custom_build

line 7, there is a duplicate letter "m" for "https://raw.521000.bestm"

Fixed. Thanks.
