Then, you would define a "diff.tex.xfuncname" configuration to
specify a regular expression that matches a line that you would
-want to appear as the hunk header "TEXT", like this:
+want to appear as the hunk header "TEXT". Add a section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
------------------------
[diff "tex"]
in the "diff.*.wordRegex" configuration variable. For example, in TeX
a backslash followed by a sequence of letters forms a command, but
several such commands can be run together without intervening
-whitespace. To separate them, use a regular expression such as
+whitespace. To separate them, use a regular expression in your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file) like this:
------------------------
[diff "tex"]
For example, to show the diff of the exif information of a
file instead of the binary information (assuming you have the
-exif tool installed):
+exif tool installed), add the following section to your
+`$GIT_DIR/config` file (or `$HOME/.gitconfig` file):

[diff "jpg"]
