Knitting pattern query

Hello all
My name is Emily and I was hoping for some help reading a pattern
It’s a 4 year olds jersey.

It reads
Garter stitch until peace measures 22cm.
End with a WS row
Cast on 5 stitches beg next 4 rows. 67 stitches.

Please can someone help me decipher that
I am a little lost.
Thank you

Hi and welcome!
Here’s how to cast on at the beginning of a row. I’m not sure if that’s what is causing you problems or not but just let us know:

If this knit cast on is too fast, you can slow it down in the settings icon.

Thank you so much
That’s a huge help

Pleasant day
