Because you call the minor chords a new chapter, it sounds as though you may already know the chords of the harmonised major scale:
I ii iii IV V vi vii(dim) I
(In case that's not familiar upper case is major and lower case is minor)
and to put it in the key of C:
C Dm Em F G Am Bdim C
So, the first thing to learn about about the minor is that the scales are the same as the major but they start on the 6th:
vi vii(dim) I ii iii IV V vi
which you may see written (to reflect the fact that they key is minor so the 'one' should be minor)) as:
i ii III iv v VI VII i
Or in the key of A minor (which has the same chords as the key of C):
Am Bdim C Dm Em F G Am
May be a helpful start or may be a patronising load of you-know-what because you already knew all that
