Emphasis on being plural.
Working in G Major:
G A B C D E F# G
For A Dorian some would say "play G Major from A".
A B C D E F# G A
While some would start with A Major:
A B C# D E F# G# A
and say flat the 3 and 7 giving you the same result:
A B C D E F# G A
and a formula for Dorian:
1 2 b3 4 5 6 b7
Now do the same with the chords of G Major
G Am Bm C D Em F#dim
SHR for Major/Ionian: I, IV and V are Major; ii, iii, vi are minor and vii is diminished
V chord will become Dominant 7
(All 7 chords are V chords only applies to Major/Ionian)
For Dorian start with the second chord, Am
Am Bm C D Em F#dim G
Since C is a b3 compared to A Major the C chord can be considered a bIII chord.
Likewise the G chord can be considered a bVII chord since it is built on the b7 of the Dorian scale.
SHR for Dorian: III, IV and VII are Major, i, ii and v are minor and vi is diminished
IV chord will become Dominant 7
Continue the process with Bm as the i chord, then C as I, D as I.
Here's Em as i (which will also yield the SHR for Natural/Relative Minor; GTMU Lesson 16)
Em F#dim G Am Bm C D
SHR for Aeolian: i, iv and v are minor; III, VI and VII are Major (also considered bIII, bVI and bVII) and ii is diminished.
bVII chord will become Dominant 7.
Maybe check out the AAP Theory session from 9-16-21: Power Chord Harmony
I wasn’t allowed into the recent discussion concerning the “cheat sheet” related to this topic.
I just think the derivation of that chart is easier to understand if you “plug in” actual chords.
