I need help with a baby bootie pattern!! =/

[offthaneedle]

hello all!
thank u for taking the time to read this post! is there someone out there that can help?? i really, really need help with this part of the pattern for a baby bootie i really want to crochet! your help is greatly appreciated!

Here is part of the pattern:
SIDES AND SOLE
rnd 1: ch 27, loosely, skip next 7 dc, being careful not to twist ch, slip st in next dc, place marker around dc just worked into for st placement; ch 3, dc in next 23 dc and in marked dc, do not remove marker, dc in each ch around; join with slip st to first dc: 52 dc.

I have tried this once before and failed. I do not understand if you crochet in the same space as the ch 27 and also when u work around, i did not get 52 dc. Also, I do not understand where it says slip st in next dc, place marker around dc just worked into for st placement.

Thank you so much to whoever can help!!
