Pattern help connecting in the round

I'm new to crocheting. I don't understand which stitches these are referring to when joining round to round:

The shell pattern is 2 dc, ch 1, 2 dcs

Chain 5 and join with sl st in first chain to form a ring - No problem here.

Round 1- Ch 3, dc in ring, ch 1, [work 2 dcs in ring, chain 1] three times, join with sl st in top of beginning ch 3; 8 dcs and 4 ch-sps. Question: which is the top stitch of beginning ch 3?

Round 2 - Sl st to ch-sp, ch 3, work 1 dc, ch1, 2 dcs in same ch-sp (SH made) * work SH in next ch-sp: repeat from * around, join with sl st in stop of beginning ch-3; 4 shells. Questions: at beginning of row - what does it mean to "sl st to ch-sp" and at end of row - "sl st in stop of beginning ch-3"?

Round 3 - "Sl st to ch-sp of next SH"

Thanks for help provided

Round 1- Ch 3, dc in ring, ch 1, [work 2 dcs in ring, chain 1] three times, join with sl st in top of beginning ch 3; 8 dcs and 4 ch-sps. Question: which is the top stitch of beginning ch 3? -- At the beginning of this round you did a ch-3 to raise your work up from the initial ring. The chain that is next to the top of your first dc is the chain into which you slip stitch to close up round 1.

Round 2 - Sl st to ch-sp, ch 3, work 1 dc, ch1, 2 dcs in same ch-sp (SH made) * work SH in next ch-sp: repeat from * around, join with sl st in stop of beginning ch-3; 4 shells. Questions: at beginning of row - what does it mean to "sl st to ch-sp" -- On your previous round, you started with a ch3, dc, ch1. When you chain into the third chain of your ch3 you are now next to the dc. Slip stitch into the top of the dc and then slip stitch into that space you created with the ch-1. What you are doing is working across the top of stitches and chain spaces to move the start of your next round into the ch-1 space, instead of starting your next round on the original chain 3.

As usual, KT's instructions are spot-on, but if it would help to see an illustration, Google "crochet in the round tutorial" and you'll be directed to any number of sites which will supply you with illustrations and even videos.
