How can I use pagination on Post

Hello there,

I have a nice pagination on Category

http://www.universewithme.com/?cat=249

You can see what I mean on the link.

There is pagination on the button.

I can also see that there is tags of pagination on funtion.php

The problem is how I can use pagination on Post.

I tried many things on single.php.

But nothing is working.

What I need? What is tag for using pagination??

Please, help me!!

Thanks,

Jin
