Hi and welcome to KH!
It sounds like you have 4 markers on the needles already and you're going to be adding in some more to define the front bands. The directions in brackets are repeated 4 times (basically you're increasing one stitch before and one stitch after the marker).
So the directions are:
K2, p1, k2 (This will be one front band), place marker,
[k to 1 st before marker, M1, k1, slip marker, k1, M1] 4 times ,
k to last 5 sts, place marker,
k2, p1, k2 (This is the other front band)
You will have increased 8 sts across this row.
For the increases you could do a Make one left
shown on the Free Videos tab, Increaes, at the top of the page.
Take it step-by-step and I think it'll start to make sense. This increase pattern will probably continue throughout the sweater yoke.
