+-- == Generic Configuration ==
+
+-- only accept queries (Do53, DNSCrypt,  DoT or DoH) from a few subnets
+-- see https://dnsdist.org/advanced/acl.html for more details
+-- please be careful when dnsdist is deployed in front of a server
+-- server granting access based on the source IP, as all queries will
+-- seem to originate from dnsdist, which might be especially relevant for
+-- AXFR, IXFR, NOTIFY and UPDATE
+-- https://dnsdist.org/advanced/axfr.html
+-- setACL({'192.0.2.0/28', '2001:DB8:1::/56'})
+
+-- listen for console connection with the given secret key
+-- https://dnsdist.org/guides/console.html
+-- controlSocket("127.0.0.1:5900")
+-- setKey("please generate a fresh private key with makeKey()")
+
+-- start the web server on port 8083, using password 'set a random password here'
+-- https://dnsdist.org/guides/webserver.html
+-- webserver("127.0.0.1:8083", "set a random password here")
+
+-- send statistics to PowerDNS metronome server https://metronome1.powerdns.com/
+-- https://dnsdist.org/guides/carbon.html
+-- carbonServer("37.252.122.50", 'unique-name')
+
+-- accept plain DNS (Do53) queries on UDP/5200 and TCP/5200
+-- addLocal("127.0.0.1:5200")
+
+-- accept DNSCrypt queries on UDP/8443 and TCP/8443
+-- https://dnsdist.org/guides/dnscrypt.html
+-- addDNSCryptBind("127.0.0.1:8443", "2.provider.name", "DNSCryptResolver.cert", "DNSCryptResolver.key")
+
+-- accept DNS over TLS (DoT) queries on TCP/9443
+-- https://dnsdist.org/guides/dns-over-tls.html
+-- addTLSLocal("127.0.0.1:9443", {"server.crt"}, {"server.key"}, { provider="openssl" })
+
+-- accept DNS over HTTPS (DoH) queries on TCP/443
+-- https://dnsdist.org/guides/dns-over-https.html
+-- addDOHLocal("127.0.0.1:443", {"server.crt"}, {"server.key"})
+
+-- define downstream servers, aka backends
+-- https://dnsdist.org/guides/downstreams.html
+-- https://dnsdist.org/guides/serverpools.html
+-- https://dnsdist.org/guides/serverselection.html
+-- newServer("192.0.2.1")
+-- newServer({address="192.0.2.1:5300", pool="abuse"})
+
+-- == Tuning ==
+
+-- Increase the in-memory rings size (the default, 10000, is only one second at 10k qps) used by
+-- live-traffic inspection features like grepq, and use 100 shards to improve performance
+-- setRingBuffersSize(1000000, 100)
+
+-- increase the number of TCP workers, each one being capable of handling a large number
+-- of TCP connections since 1.4.0
+-- setMaxTCPClientThreads(20)
+
+-- == Sample Actions ==
+
+-- https://dnsdist.org/rules-actions.html
+
+-- send the queries for selected domain suffixes to the servers
+-- in the 'abuse' pool
+-- addAction({"abuse.example.org.", "xxx."}, PoolAction("abuse"))
+
+-- drop queries for this exact qname
+-- addAction(QNameRule("drop-me.example.org."), DropAction())
+
+-- send the queries from a selected subnet to the
+-- abuse pool
+-- addAction("192.0.2.0/24", PoolAction("abuse"))
+
+-- Refuse incoming AXFR, IXFR, NOTIFY and UPDATE
+-- Add trusted sources (slaves, masters) explicitely in front of this rule
+-- addAction(OrRule({OpcodeRule(DNSOpcode.Notify), OpcodeRule(DNSOpcode.Update), QTypeRule(DNSQType.AXFR), QTypeRule(DNSQType.IXFR)}), RCodeAction(DNSRCode.REFUSED))
+
+-- == Dynamic Blocks ==
+
+-- define a dynamic block rules group object, set a few limits and apply it
+-- see https://dnsdist.org/guides/dynblocks.html for more details
+
+-- local dbr = dynBlockRulesGroup()
+-- dbr:setQueryRate(30, 10, "Exceeded query rate", 60)
+-- dbr:setRCodeRate(dnsdist.NXDOMAIN, 20, 10, "Exceeded NXD rate", 60)
+-- dbr:setRCodeRate(dnsdist.SERVFAIL, 20, 10, "Exceeded ServFail rate", 60)
+-- dbr:setQTypeRate(dnsdist.ANY, 5, 10, "Exceeded ANY rate", 60)
+-- dbr:setResponseByteRate(10000, 10, "Exceeded resp BW rate", 60)
+-- function maintenance()
+--  dbr:apply()
+-- end
+
+-- == Logging ==
+
+-- connect to a remote protobuf logger and export queries and responses
+-- https://dnsdist.org/reference/protobuf.html
+-- rl = newRemoteLogger('127.0.0.1:4242')
+-- addAction(AllRule(), RemoteLogAction(rl))
+-- addResponseAction(AllRule(), RemoteLogResponseAction(rl))
+
+-- DNSTAP is also supported
+-- https://dnsdist.org/reference/dnstap.html
+-- fstr = newFrameStreamUnixLogger(/path/to/unix/socket)
+-- or
+-- fstr = newFrameStreamTcpLogger('192.0.2.1:4242')
+-- addAction(AllRule(), DnstapLogAction(fstr))
+-- addResponseAction(AllRule(), DnstapLogResponseAction(fstr))
+
+-- == Caching ==
+
+-- https://dnsdist.org/guides/cache.html
+-- create a packet cache of at most 100k entries,
+-- and apply it to the default pool
+-- pc = newPacketCache(100000)
+-- getPool(""):setCache(pc)
