 USAGE
 -----
 
+Using of it is [highly appreciated](http://twister.net.co/?p=410). If you
+have a 24×7 machine and you are able to add an special NS record to your domain,
+please consider running twister-seeder. Then let @miguelfreitas know
+and he will add your domain to the code base.
+
 Assuming you want to run a dns seed on dnsseed.example.com, you will
 need an authorative NS record in example.com's domain record, pointing
 to for example vps.example.com:
 
-$ dig -t NS dnsseed.example.com
+    dig -t NS dnsseed.example.com
+
+As answer you should get something like this:
 
-;; ANSWER SECTION
-dnsseed.example.com.   86400    IN      NS     vps.example.com.
+> dnsseed.example.com.   86400    IN      NS     vps.example.com.
 
 On the system vps.example.com, you can now run dnsseed:
 
     ./dnsseed -h dnsseed.example.com -n vps.example.com
 
 If you want the DNS server to report SOA records, please provide an

 RUNNING AS NON-ROOT

 One solution is using an iptables rule (Linux only) to redirect it to
 a non-privileged port:
 
-$ iptables -t nat -A PREROUTING -p udp --dport 53 -j REDIRECT --to-port 5353
+    iptables -t nat -A PREROUTING -p udp --dport 53 -j REDIRECT --to-port 5353
 
 If properly configured, this will allow you to run dnsseed in userspace, using
 the -p 5353 option.
