+================

+NAME
+----
+git-diagnose - Generate a zip archive of diagnostic information
+
+SYNOPSIS
+--------
+[verse]
+'git diagnose' [(-o | --output-directory) <path>] [(-s | --suffix) <format>]
+	       [--mode=<mode>]
+
+DESCRIPTION
+-----------
+Collects detailed information about the user's machine, Git client, and
+repository state and packages that information into a zip archive. The
+generated archive can then, for example, be shared with the Git mailing list to
+help debug an issue or serve as a reference for independent debugging.
+
+By default, the following information is captured in the archive:
+
+  * 'git version --build-options'
+  * The path to the repository root
+  * The available disk space on the filesystem
+  * The name and size of each packfile, including those in alternate object
+    stores
+  * The total count of loose objects, as well as counts broken down by
+    `.git/objects` subdirectory
+
+Additional information can be collected by selecting a different diagnostic mode
+using the `--mode` option.
+
+This tool differs from linkgit:git-bugreport[1] in that it collects much more
+detailed information with a greater focus on reporting the size and data shape
+of repository contents.
+
+OPTIONS
+-------
+-o <path>::
+--output-directory <path>::
+	Place the resulting diagnostics archive in `<path>` instead of the
+	current directory.
+
+-s <format>::
+--suffix <format>::
+	Specify an alternate suffix for the diagnostics archive name, to create
+	a file named 'git-diagnostics-<formatted-suffix>'. This should take the
+	form of a strftime(3) format string; the current local time will be
+	used.
+
+--mode=(stats|all)::
+	Specify the type of diagnostics that should be collected. The default behavior
+	of 'git diagnose' is equivalent to `--mode=stats`.
++
+The `--mode=all` option collects everything included in `--mode=stats`, as well
+as copies of `.git`, `.git/hooks`, `.git/info`, `.git/logs`, and
+`.git/objects/info` directories. This additional information may be sensitive,
+as it can be used to reconstruct the full contents of the diagnosed repository.
+Users should exercise caution when sharing an archive generated with
+`--mode=all`.
