Tulsa Tank pattern

Hi, new here and hoping to get some help with the pattern I am working on. I’ve come to a part that I don’t understand.

pattern reads:

Mark center 10(10,10) sets.

NEXT ROW (RS): work in patt as est to first m, rm, place 22 sets just worked on hold for left front next, BO to second m, rm, work to end. 22 sts rem for right front neck.

there in no place in which it says to add and markers. but it mentions 2 markers in the next row paragraph. also not sure what is meant by Mark center 10.

not sure where the 2 markers are placed to begin with.

would appreciate any help. this pattern is off of Ravelry.

thank you so much.

Welcome to KnittingHelp!
The pattern is telling you to place markers on either side of the middle 10sts. It seems that you should have 54sts. Count off 22sts, place a marker, count off another 10sts, place the second marker. There will be 22sts to the end of the row.
Follow the directions in the Next Row. You’ll be binding off the center 10sts and end with 22sts on each side for the right and left shoulders.

What is the name of your pattern?
