Chord name
There is the name of a chord before the symbols. If it's "*" added to a name, it means that this chord is played in different positions during the song.
Chord designation
There are 6 symbols in a designation, read it from left to right. The first symbol defines the thickest string (6th string), the second symbol defines 5th string and so on.
"0" means open string
"x" means this string isnt played
"Number" means number of a fret.
Example:

6th string isnt played
5th string is open
4th string is played on 2nd fret
3rd string is played on 2nd fret
2nd string is played on 2nd fret

Chord scheme
Imagine that you are looking at the fret while playing guitar - the closest string to your eyes is the 6th, the thickest string. There are 6 horizontal lines defines strings, the upper one is the thinnest string (1st string).
And there are 4 lines defined frets - no exact frets numbers defined.
In some schemes there is a thick line on the left - it defines the nut.
- "0" means open string
- "x" means this string isnt played
- Fat dots mean fingers positions
Example:
G5 355xxx
