How to use Group Manager mirroring

I want to use GroupManager mirroring to give each world a specific kit.
So when they go into the factions world, they'll get a starter kit, like /kit Factions
Then for survival a kit like, /kit survival
etc.
Can anyone help me with this?

 

Unmirror the groups.yml for each world and give different permissions in them.

Can you give me a little bit more information, I'm like a pure noob at this xD.
Also if you want to help me out quicker instead of replying at different times you can add me on skype,

at config.yml, instead of having both groups and users mirrored, mirror just users. each world will have its own groups.yml, modify at your will.
