How do you use Nintendo wi-fi?

Answer:
cant explain.if you have a DS game it has insructions

First off, look to see if the game has a blue circle in the top left corner of the case. If it does, read the instruction manual for details. If it does not, it is not compatible with Wi-Fi. This works for Wii or DS games.
