How to knit a neat V-neck ribbing

When knitting a V-neck sweater you need a neat finish for the neck ribbing. Of course, you could do it in two pieces which overlap, but for the classic finish like above you need to decrease in a special way. I used this neckline finish on my Phildar 093/30 baby pullover.
To be honest, when doing some research I found most written instructions confusing, and the original Phildar instructions didn't work for me, while the technique itself is relatively easy.

• You work from the bottom up (you can either pick up stitches along the edge of the V-neck or knit your ribbing separately and attach it later)
• To make this finish you need to decrease one stitch in every row, both on the right side and the wrong side of the work
• you need a cable needle or an extra needle (I used a short sock-needle)

step-by-step instructions:
It looks like there are a lot of steps, but basically you just need to twist your stitches before knitting, like you would do when knitting cables.
Important:

• You need to pick up an uneven amount of stitches
• You want to be the center stitch of your ribbing (on the right side) a knit stitch. To do this start the first and every row on the right side with two knit stitches and then rib, alternating purl 1, knit 1 

On the right side:
- rib until you reach the 3 center stitches, then slip the next stitch to the right needle:


- place the next (center) stitch on a cable needle in front of the work:

- slip the next (3rd) stitch to the right needle:

slip the center stitch back to the left needle:

- then slip the other stitches back on the left needle as well:

- knit the 3 stitches together:

On the wrong side:
- when you reach the 3 center stitches, slip the next stitch to the right needle:


- place the next (center) stitch on a cable needle at the back of the work:

- slip the first stitch from the right needle back to the left needle:

- finally slip the center stitch from the needle back on the left needle as well:

- purl the 3 stitches together:

Continue to the desired length, cast off loosely.
The result will be a straight line of neat knit stitches in the center front:


Here is how it looks from the wrong side:
