             Description

            
              Blank Line
               Match no files - can serve as a separator for readability.

            
              Lines starting with hash(#)
               Comment by default.

            
              Trailing spaces
               being ignored unless they are quoted with backslash (\).

            
              !
               Negates the pattern.

               match directory and any paths under it.

            
              No slash(/)
               match pathname relative to .gitignore file or the top-level of the work tree if not from .gitignore.
