So you just got resident and want to make a store. Th
e first obvious step is find somewhere to place your store. If you have tp, it really doesn't matter, but in a popular place is a good idea. Good ideas include build gates, spawn markets, or in a town. Then get plenty of supplies. You will need tons, if you plan on mamking a lot of money. Get things that people want like diamonds and tools. Then make a trade sign like so:

[Trade]
(The amount of money selling for)
(quantity selling) (Id number) : (Total in stock)
Make sure you have that item in your inventory.

If you want to see my store I made, pm me for a tp. Otherwise, I hope this helps everyone!
