There are different formats; original, 'diff -c', 'diff -u'.
You should be able to figure the format out by looking at some
examples (like in the archives of this list), at least for the
latter two.

Seems to be similar in pronciple, except that diff just acts on
files as text, an on a line by line basis.

See your friendly UNIX shell account for man pages (man diff, man

man pages or info files).
