Go to the full guitar chords tutorial.
The A augmented chord (Aaug) combines A, C# and E#, that is the root, major third and raised fifth. The raised fifth is what separates it from a major chord: the root and third stay, and only the fifth moves up a semitone.
Notes such as E# are written that way to keep one letter name per chord tone, even though they sound like simpler notes. The page lists 4 voicings: one rings an open string and one is a barre shape. Melodies over Aaug can draw on the A whole-tone scale, which contains every note of the chord.
The fretboard player at the top labels every note of each shape, so you can see where the root and the other chord tones sit.
A augmented guitar chord is also written as Aaug, A+, A(#5) or Amaj(#5).
