Cutting Nails

How should one cut ones nails according to Jewish law? thank you!

The Rama writes that one should not cut nails in order, as this leads to poverty (דרכי משה רמא).  The Rama specifies an order for cutting one’s nails. Starting with the left hand, the order to cut is ring, index, pinky, middle and thumb. On the right hand one cuts the index, ring, thumb, middle and pinky.

The Chazon Ish rules that one must cut their nails as described only when cutting the finger nails. When cutting toenails one may cut in any order.
