Having trouble with E-Q->Flash ;-;

Hi all, I've been trying to learn yasuo recently. Particularly the E-Q-Flash combo, I cant seem to get it down with a success rate of 1 out of every 30 attempts. I don't know what I am doing wrong. Could anyone go step by step and help me out? Also is there a discord? I cant see it on the right-hand side.

Thanks for everything.
