Setting your shop

   There are many shops in Minecraftia, and you can be owner of one of them! But, obviously, you need to know how they work.
   You just need a sign and a chest.

•    Leave the first line empty;  
•    In the second line type the ammount you wanna sell each time. ex.: 64;
•    In the third line type the price you want people to buy and the price you want them to sell, separated by ":". ex.: 10:5

•    Finnaly, in the fourth line type the ID of the item you wanna sell/buy. ex.: 1 (Stone).
