+DISCUSSION
+----------
-NOTES
------
+Commit notes are blobs containing extra information about an object
+(usually information to supplement a commit's message). These blobs
+are taken from notes refs. A notes ref is usually a branch which
+contains "files" whose paths are the object names for the objects
+they describe, with some directory separators included for performance
+reasons footnote:[Permitted pathnames have the form
+'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
+names of two hexadecimal digits each followed by a filename with the
+rest of the object ID.].
Every notes change creates a new commit at the specified notes ref.
You can therefore inspect the history of the notes by invoking, e.g.,
-`git log -p notes/commits`.
+`git log -p notes/commits`. Currently the commit message only records
+which operation triggered the update, and the commit authorship is
+determined according to the usual rules (see linkgit:git-commit[1]).
+These details may change in the future.
+
+It is also permitted for a notes ref to point directly to a tree
+object, in which case the history of the notes can be read with
+`git log -p -g <refname>`.
+
+
+EXAMPLES
+--------
+
+You can use notes to add annotations with information that was not
+available at the time a commit was written.
+
+------------
+$ git notes add -m 'Tested-by: Johannes Sixt <j6t@kdbg.org>' 72a144e2
+$ git show -s 72a144e

+------------
+
+In principle, a note is a regular Git blob, and any kind of
+(non-)format is accepted. You can binary-safely create notes from
+arbitrary files using 'git hash-object':
+
+------------
+$ cc *.c
+$ blob=$(git hash-object -w a.out)
+$ git notes --ref=built add -C "$blob" HEAD
+------------
+
+Of course, it doesn't make much sense to display non-text-format notes
+with 'git log', so if you use such notes, you'll probably need to write
+some special-purpose tools to do something useful with them.
+
+
+CONFIGURATION
+-------------
-Currently the commit message only records which operation triggered
-the update, and the commit authorship is determined according to the
-usual rules (see linkgit:git-commit[1]). These details may change in
-the future.
+core.notesRef::
+ Notes ref to read and manipulate instead of
+ `refs/notes/commits`. Must be an unabbreviated ref name.
+ This setting can be overridden through the environment and
+ command line.
+
+notes.displayRef::
+ Which ref (or refs, if a glob or specified more than once), in
+ addition to the default set by `core.notesRef` or
+ 'GIT_NOTES_REF', to read notes from when showing commit
+ messages with the 'git log' family of commands.
+ This setting can be overridden on the command line or by the
+ 'GIT_NOTES_DISPLAY_REF' environment variable.
+ See linkgit:git-log[1].
+
+notes.rewrite.<command>::
+ When rewriting commits with <command> (currently `amend` or
+ `rebase`), if this variable is `false`, git will not copy
+ notes from the original to the rewritten commit. Defaults to
+ `true`. See also "`notes.rewriteRef`" below.
++
+This setting can be overridden by the 'GIT_NOTES_REWRITE_REF'
+environment variable.
+
+notes.rewriteMode::
+ When copying notes during a rewrite, what to do if the target
+ commit already has a note. Must be one of `overwrite`,
+ `concatenate`, and `ignore`. Defaults to `concatenate`.
++
+This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
+environment variable.
+
+notes.rewriteRef::
+ When copying notes during a rewrite, specifies the (fully
+ qualified) ref whose notes should be copied. May be a glob,
+ in which case notes in all matching refs will be copied. You
+ may also specify this configuration several times.
++
+Does not have a default value; you must configure this variable to
+enable note rewriting.
++
+Can be overridden with the 'GIT_NOTES_REWRITE_REF' environment variable.
+
+
+ENVIRONMENT
+-----------
+
+'GIT_NOTES_REF'::
+ Which ref to manipulate notes from, instead of `refs/notes/commits`.
+ This overrides the `core.notesRef` setting.
+
+'GIT_NOTES_DISPLAY_REF'::
+ Colon-delimited list of refs or globs indicating which refs,
+ in addition to the default from `core.notesRef` or
+ 'GIT_NOTES_REF', to read notes from when showing commit
+ messages.
+ This overrides the `notes.displayRef` setting.
++
+A warning will be issued for refs that do not exist, but a glob that
+does not match any refs is silently ignored.
+
+'GIT_NOTES_REWRITE_MODE'::
+ When copying notes during a rewrite, what to do if the target
+ commit already has a note.
+ Must be one of `overwrite`, `concatenate`, and `ignore`.
+ This overrides the `core.rewriteMode` setting.
+
+'GIT_NOTES_REWRITE_REF'::
+ When rewriting commits, which notes to copy from the original
+ to the rewritten commit. Must be a colon-delimited list of
+ refs or globs.
++
+If not set in the environment, the list of notes to copy depends
+on the `notes.rewrite.<command>` and `notes.rewriteRef` settings.
