Pretty old tech but I thought it would be better explained in video from so here ya go, more like this to come soon(ish).
I still don’t get the correct inputs to do this 
cr.lp xx cr.lp xx st.lk ~ mk/hk command throw
I find it easiest to do…
df+lp
df+lp
d
db
b + lk
mk or hk
All the light attacks need to be at chain speed. The last attack input (mk/hk) needs to be 2 or 3 frames after the lk. Give that a go, It’s pretty simple.
Of course for EX command throw, use st.lk~mk+hk
Will give it a try, thanks
