The chords here will be formed only using the degrees that are present in C Minor scale. And they will be named on the degree from which the chord will begin. Talking about the notations, the major chords will be represented by capital roman letters, minor chords with small letters, diminished chords with small roman letters followed by °, and augmented chords with small letters followed by +.
