Basically what zhukov said but make sure your nozzles are set at 10 degrees, as they should be set for all taxi and conventional takeoffs because it disrupts airflow over the wing/flaps.
Don't forget to trim 2 degrees nose down.
Edit: For clarity you can use more nozzle than 10 degrees during taxi but you should use no less than 10 degrees nozzle with flaps at 25 degrees.
