The rules

Start from a triad
Root, 3rd and 5th, stacked in thirds. The 3rd makes it major or minor; the 5th makes it diminished or augmented when it moves.
A third on top makes a 7th chord
A major 7th over a major triad is maj7, a ♭7 is a dominant 7. Over minor you get m7 or m(maj7); over diminished, m7♭5 or the °7, whose 7th is lowered twice.
Keep stacking for extensions
The 9th, 11th and 13th are the 2nd, 4th and 6th an octave up. Each one sits on the stack below it: a 9th chord holds a 7th, a 13th holds the 9th and 11th in theory.
