Welcome to KnittingHelp!
Which size are you making? The instructions are to start the chart at the right edge, depending on the size you want. Follow the chart for the left front and do the decreases which are also noted in the chart. Row 9 is the next dec row.
The chart continues up to row and then repeats rows 63 to 86.

It’s a beautifully tailored cardigan:
