Fetch branches and/or tags (collectively, "refs") from one or more other
 	repositories, along with the objects necessary to complete their histories.
 	Remote-tracking branches are updated (see the description of <refspec>
 	below for ways to control this behavior).

 	Command Syntax:

 		git fetch [<options>] [<repository> [<refspec>…​]]
 		git fetch [<options>] <group>
 		git fetch --multiple [<options>] [(<repository> | <group>)…​]
 		git fetch --all [<options>]
