First you go to:
1 PBN Hosting
2 cPanel connector
3 chose server that you want to add your domain to (My example is pluto)
4 write down ip of that server for later (my example is 64.182.125.126)
As shown here: http://screencast.com/t/TLJQEvMT2U
5 Once you connect go to WPAmigo Domain Manager

6 Add your domains, and note that you can add max up to 3 domains
7 Once that is done go do your domain registrar. in this case I will use GoDaddy, but general work is everywhere the same.
8 Once you are in GoDaddy find your domain and click: http://screencast.com/t/1ijDAcDEeH9
9 Click on Host names to create ns1 and ns2 nameservers, pointing to the IP of the server (from step 4)

10 Once you are done it should look like this: http://screencast.com/t/Vaygh1nV Again, this is example based on server that I've chosen.
Wait up to 5 minutes to proceed to next step
11 Click on nameservers

12 And write nameservers like this ns1.YOURdomain.com ns2.YOURdomain.com PLEASE NOTE that YOURdomain.com is an example. YOURdomain.com should be replaced by your actual domain that you wrote in step 6. So, say if you owned google.com it should be ns1.google.com and ns2.google.com
After that is done, and your domain starts resolving you may proceed with installing WordPress.
And that should be it!
