This may sound sort of stupid but I have no idea how to farm or craft. Lol so I'd like to ask if someone can help me figure this out so I can try to attempt it x) thanks in advance!

To farm, you need a house with at least 1 "Garden Size" spot.
Go to "Your Home" in the top-left.
If you have a berry, you click the green square under "Your Garden" and choose "Oran Berry" as you are just starting.
As your farming level increases, you will be able to plant other things in your garden.

To craft, you need a house with at least 1 "Indoor Size" spot.
Go to "Your Home" as well.
You need a "Bowl" from "Mart Co." for $1000 and a "Fresh Water" from the "Department Store" for $250,000 & 100 coins.
Click the Indoor spot and use the first two drop-down lists to select "Fresh Water" and "Bowl" to create a "Bowl of Water".
Slowly continue to do this to increase your Crafting level to unlock new recipes.
