+Configuration
+-------------
+
+See linkgit:git-config[1] for core variables and linkgit:git-diff[1]
+for settings related to diff generation.
+
+format.pretty::
+       Default for the `--format` option.  (See "PRETTY FORMATS" above.)
+       Defaults to "medium".
+
+i18n.logOutputEncoding::
+       Encoding to use when displaying logs.  (See "Discussion", above.)
+       Defaults to the value of `i18n.commitEncoding` if set, UTF-8
+       otherwise.
+
+log.date::
+       Default format for human-readable dates.  (Compare the
+       `--date` option.)  Defaults to "default", which means to write
+       dates like `Sat May 8 19:35:34 2010 -0500`.
+
+log.showroot::
+       If `false`, 'git log' and related commands will not treat the
+       initial commit as a big creation event.  Any root commits in
+       `git log -p` output would be shown without a diff attached.
+       The default is `true`.
+
+mailmap.file::
+       See linkgit:git-shortlog[1].
+
+notes.displayRef::
+       Which refs, in addition to the default set by `core.notesRef`
+       or 'GIT_NOTES_REF', to read notes from when showing commit
+       messages with the 'log' family of commands.  See
+       linkgit:git-notes[1].
++
+May be an unabbreviated ref name or a glob and may be specified
+multiple times.  A warning will be issued for refs that do not exist,
+but a glob that does not match any refs is silently ignored.
++
+This setting can be disabled by the `--no-standard-notes` option,
+overridden by the 'GIT_NOTES_DISPLAY_REF' environment variable,
+and supplemented by the `--show-notes` option.
