Well how was I supposed to know there was a guide?

I was making a modpack for my friends server and tried testing out my pack before sending it off to him. When I loaded it I was met with vanilla 1.12.2 minecraft and dont know how to change that. I cant understand any of the other older threads made about it so a step by step would be nice. Pack: http://api.technicpack.net/modpack/havensmp
