 +==== DESCRIPTION ====
 +
 +<​code>​
 +git diff [<​options>​] <​commit>​ <​commit>​ [--] [<​path>​...]
 +    This is to view the changes between two arbitrary <​commit>​.
 +
 +git diff [<​options>​] <​commit>​..<​commit>​ [--] [<​path>​...]
 +    This is synonymous to the previous form. If <​commit>​ on one
 +    side is omitted, it will have the same effect as using HEAD
 +    instead.
 +
 +git diff [<​options>​] <​commit>​...<​commit>​ [--] [<​path>​...]
 +    This form is to view the changes on the branch containing
 +    and up to the second <​commit>,​ starting at a common
 +    ancestor of both <​commit>​. "git diff A...B" is equivalent
 +    to "git diff $(git merge-base A B) B". You can omit any one
 +    of <​commit>,​ which has the same effect as using HEAD
 +    instead.
