Now about the linking to your server part.
1st way
If you have a Hamachi server then you just put your Hamachi ip in the mc.txt
If you have a dedicated server then just give the server ip in the mc.txt.
If you have any other problems dont hesitate to text me back.
Also heres a link with a lot of usefull information its almost everything you need to know
