The SuperTrend basically follows the trend of the price. If the SuperTrend is green and below the price then it usually indicates an up trend and vice versa. The most significant part is when the line starts to go flat. It, to me at least, provides a better visual clue of trend starting to lose momentum.
Nbr_Periods: adjusts the amount of bars for calculation. (the average true range)
Multiplier: The amount to multiply the result of the avarage true range by. This result is then added to the median price of the current bar.
That's all I can really tell you.
