I have setup my two nodes with success. The tip is to create a page that will appear your bitcoin adress.
I have find very useful this guide
https://www.reddit.com/r/Bitcoin/comments/2wrmes/how_to_set_up_an_incentivized_node_in_ubuntu/but in the last command i have use this
https://bitnodes.21.co/api/#node-bitcoin-addresscurl -H "Accept: application/json; indent=4" -d "bitcoin_address=137SdnVDqHdtT5b4UuK4mctua4WJ3z6BKa" -d "url=http://148.251.238.178"
https://bitnodes.21.co/api/v1/nodes/148.251.238.178-8333/you replace your adress, ip etc.
In the reddit guide it says how you can create a simple page. One other option is to install apache2 and after that if you have ubuntu you go to the folder
/var/www/html//var/www/html/
and you create there a simple index.html file with your bitcoin address.
For the windows users i have found this guide but i dont know if it works
