as a Roman numeral progression it is either vi-V-ii7-I or i-bVII-v7-IV
if there is a "m" next to a note name the chord is minor
unless it is shown as mb5 (diminished triad) or m7b5 (minor 7 b5 or half-diminished 7th)
if there is not then it is major
unless there is a "(#5)" next to it then it is an augmented chord - #5 is presented in sidne teh parentheses to distinguish the # that may naturally occur in some chord names e.g. F#(#5) is F# augmented consisting of F#-A#-C# whereas F#5 is a F# power chord consisting only of F# and C#
the number 7 indicates that there are four notes in the chord - depending on context these are mostly going to be a minor 67th above the root of the chord
the ~ is used to separate the chord name from the notes need to make that chord: e.g. F#m ~ F#-A-C# should be read as "F#m consists of F#-A-C#"
