Help with stutter stepping and configuration

So basically let me get to the point , i've been looking into this for a while but ive been playing with the default set ups since season 1. i hear people who play adc and such can change the mouse buttons , for instance Mb1 to move and mb2 to attack or something like that...idk its hard to explain and understand for me...i have gotten use to using shift MB2 but i feel like its to much of a hassle if i were to play vayne or khalista.i dont use A+Mb1 click because it feels more difficult in my opinion. i wanna know how to make vayne a bit more easier to use with stutter stepping but dont know how and what binds to use. Help is appreciated and welcome :)
