[How to make it multiplayer]

hi so this mod is amazing and perfect for me and my friend to once again enjoy minecraft.

Can someone tell me how to set this up in multiplayer? (yes i know how to port forward and all that junk) so far all i can get it to do is singleplayer. Actually the only modpack i know how to do multiplayer is tekkit.

i recently started using tekkit.. not quite sure how to do everything yet.
