See the "Sticky" topics? Read them, always.

yeah but when im in the game do i type anything?

No. Mods start working immediately.

To get the items in a mod you can dig and craft or use the -- /giveme modname:itemname amount of items --

example: /giveme default:dirt 99

edit: Start with pressing the / on your keyboard
