It is kind if weird but to get help on parted commands, device parameter is must.

parted [device] help [command]

Command can be resizepart, mkpart, print etc. (You can get the list of all commands using parted -h)

e.g. parted /dev/sda help resizepart

# parted /dev/sda help resizepart
  resizepart NUMBER END                    resize partition NUMBER

    NUMBER is the partition number used by Linux.  On MS-DOS disk labels, the primary partitions number from 1 to 4, logical partitions from 5 onwards.
        END is disk location, such as 4GB or 10%.  Negative value counts from the end of the disk.  For example, -1s specifies exactly the last sector.
