Picking up stitches for a slipper

#1

I am knitting a slipper. I have knitted and finished the sole (which I casted off) the pattern is now telling me to “pick up and knit 2 stitches from the heel, 36 from the edge of the sole, and 4 from the toe”

What 2 stitches from the heel? I do not understand any of what it is telling me to do! Please help!

You’re to create new stitches around the edges of the slipper sole. Here’s a video for picking up and knitting sts. You can use markers to help space out the sts approximately evenly along the edge.
