Understanding a vest pattern

[freefika]

Hi all...im new to knitting...havent really done much projects apart from a baby cap and booties...now im making a vest for a 1 yr old...i have started with the back of the vest...im done with shaping the armholes as well...following which the pattern reads:

continuing with pattern without shaping until armholes measure 6 inches ending ws row...

ive done the above and am left with 36 stitches

Cast off 36 stitches, placing markers to indicate back of neck at each side of centre 22 sts.

i dunt get what the above line means abt placing the markers...where should i place them? help plz...

Figure out where the center 22 sts are (7 sts in from each end) and place the markers there.

[freefika]

does that mean i will place 2 markers on the piece on the 7th stitch from both ends?

Place the markers on the needles between the 7th and 8th sts.
