Yoo! MCbuilderN00b welcome to PMC depending what you want to do here depends on what you should know but since you haven't specified anything yet so I'll tell you the basics.

Well to start you can search up content and post it if you plan on posting mods or addons or realy anything I would start simple and format your descriptions kinda like this-

Intro: Hellooo! Welcome to the PMC intro addon this addon shows intros in game!

TIP: This is an example tip I sometimes add these.

Things to keep in mind:
1 - This pack is fake and was never made.
2 - This pack it protected under a legal license agreement and any breaking of it's terms will result in immediate legal action!
3 - Steal the pack I steal your life :) (I got this from another creator and it tends to work well.)

Outro (Not always needed): So what ye waiting for mate get this fake pack and forget about it in a few days.

Hello there, and welcome to PMC!
