Just start off picking chords one note at a time at a slow speed and then build up.

its easy, choose an arpeggio you wanna work on, start off with 3 notes, start slowly, and learn to rake pick each note INDIVIDUALLY.

you can find plenty of lessons on youtube about it

i guess that big thread at the top of the forum that has big all caps letters that say SWEEP PICKING didn't do it for ya.

I'm just playin with ya, but seriously, there is a thread at the top of the forum that says "The Sweep Picking Thread! Read For How To Sweep!" and it is stickied.
