The “C, A, G, E and D shapes” are the CAGED system: you slide the shape of the open C, A, G, E or D chord up the neck and your index finger (a barre) takes over the job of the nut. That way the same chord can be played in five places, anywhere on the fretboard.
Tuning: E A D G B E (low to high). String 6 is the thickest, the low E. In the diagram, × means the string is not played, and a circle means an open string.
Playing Cmaj7 with a capo
A capo clamps all the strings at one fret, so a familiar open shape sounds higher. You can also get a Cmaj7 chord with these open shapes:

How do I read the chord diagram?
Strings run from the lowest (left) to the highest (right) – tick “Left-handed” to mirror it. Rows are frets; a number at the side shows the starting fret. Dots are fingers (1 index, 2 middle, 3 ring, 4 little), a long bar is a barre, × means don't play that string and ○ means play it open.
Why is a note missing from some Cmaj7 shapes?
On a fretted instrument you can't always play every note of a 4-note chord. The fifth (G) may be dropped – the chord keeps its character without it.
How is the Cmaj7 chord written?
The chord symbol is Cmaj7, and its full name is C major seventh.
