+##
+## KadNode is a P2P DNS resolver to resolve domains using the BitTorrent network.
+##
+
+config kadnode
+	option enabled 1
+
+
+## ECC Key usage:
+## 1. Create public/secret key pair with `kadnode --bob-create-key /etc/kadnode_secret.pem`
+## 2. Put the secret key file on the router that you want to resolve to and use it for option bob_load_key.
+## 3. Use the public key hex output with .p2p attached on other devices to resovle to the router IP address via kadnode.
+
+## Secret key for public key links
+#	list bob_load_key '/etc/kadnode_secret.pem'
+
+
+## TLS usage:
+## For resolving domains, put credentials on the router and use option tls_client_cert.
+## For announcing domains, put the certificates and secret key on router and use option tls_server_cert.
+
+## Folder of CA certificates
+## Install package 'ca-certificates' for the official CA set.
+#	list tls_client_cert '/etc/ssl/certs'
+
+## Server credentials
+#	list tls_server_cert '/ect/mynode.crt,/etc/mynode.key'
+
+
+## Add domains to be announced.
+## Note: Only needed in special situations since tls_server_cert and bob_load_key announce automatically its associated domains.
+#	list announce 'web.myname.p2p'
+
+## Load and store good nodes every 24h and on start/shutdown.
+#	option peerfile '/etc/kadnode/peers.txt'
+
+## Add static peers addresses.
+	list peer 'bttracker.debian.org:6881'
+	list peer 'router.bittorrent.com:6881'
+
+## Bind the DHT to this port.
+#	option port '6881'
+
+## Limit DHT communication to this interface.
+#	option ifname 'eth0'
+
+## Verbosity: quiet, verbose or debug
+#	option verbosity 'quiet'
+
+## Local port to accept forwarded requests.
+#	option dns_port '3535'
+
+## Disable multicast peer discovery on the LAN.
+#	option lpd_disable '1'
+
+## Disable port forwarding when this router is behind another
+## router in a private network that supports UPnP/NAT-PMP.
+#	option fwd_disable '1'
