Putting mods on the server

Hi,
I'm quite new to this and I just set up a Vault Tec server with Hamachi. I was now wondering how I can get the server to load my mods aswell... I filled out the mod list in the vaultserver file but it still wont load the mods. I also didnt really get in which folder I have to put them to, I can find a mods folder anywhere and I dont know where I should create one. I'm sorry if these questions might be stupid, but I'm really new to this!
Any help is greatly appreciated!

Maybe you send me your skype, and we playing together?
