(BASIC) how to use arduino uno and mosfet switch to control 12V motor

This may sound basic but i have an arduino uno and i want to control this https://lincolnrobotics.wikispaces.com/12-V+DC+Motor. Its 12V and and need it to be able to change directions. Is there any code and or setip that could help with this

Also the motor has no electronics in it, it just needs 12V and it will move but i just need it to be able to change directions

You will need an H bridge controller to be able to run both ways. The H bridge will need to be able to handle the required continuous current of the motor as well as the brief stall current at startup.
