This is pretty simple pattern

Chain 4 and join with a ss to first ch to form a ring.
ch5 (counts as 1 dc and a 2-ch sp),(3 dc in ring,2 ch (these 2-ch form a corner sp]) 3 times,2 dc in ring , join with a ss to third of ch.

Step 1: Round Two:

Ss into next sp, 5ch (counts as 1dc and 2ch), 3dc into
same sp *1ch, skip 3 dc, [3dc, 2ch, 3dc] into next sp; rep from
*twice more, 1ch skip 3 dc sts, 2dc into same sp as 5-ch at
Beg of round,ss into 3rd of 5-ch

Step 2: Round 3:

Ss into next sp, 5ch(counts as 1dc and 2ch) 3dc into
Same sp, *1ch, skip 3 dc, 3 dc into next sp, 1ch , skip 3 dc **,
[3dc, 2ch, 3dc] into next sp;rep from *twice more and from * to
**? once more, 2dc into same sp as 5-ch,ss into 3rd of 5-ch.
