Abbreviation help

[VickiIL]

I am getting ready to start a poncho and was pre-reading the pattern. There is an abbreviation I am not sure if I am understanding correctly. The directions are

*K20, kpk in next stitch* repeat 3 times (end at the beginning)
ok I don't get this. Is kpk knit, purl, knit? If so I am actually increasing 2 instead of 1 correct. Also what does she mean by end at the beginning?
:thinking:
