Some advice:

1. The better questing questline that is a part of the pack is optional, but it is a great way to get your feet wet in the different mods of the pack.

2. If you want to see more of what a particular mod can offer you, type "@[modnamehere]" into the JEI search bar to the bottom right of your inventory (example: "@botania"). Don't use a space unless you want to look for an item/block inside of a mod (example: "@botania petal").

3. If you want more in-depth knowledge on a mod, look it up on youtube. I suggest Mischief of Mice or DireWolf20 for mod spotlights, though you can find other channels for the content as well.

4. Don't forget to claim chunks for yourself (or your team). When your inventory is open, an icon on the left side of your screen will read "claimed chunks." Left-click (and drag) will claim chunks, shift+left-click (and drag) will keep claimed chunks chunk-loaded, and right-click (and drag) will unclaim and/or unload chunks. Claiming chunks help prevent your chunks from being griefed, and loaded chunks help keep your automation working, even when you aren't online.
