+================
+
+NAME
+----
+git-ls-remote - List references in a remote repository
+
+
+SYNOPSIS
+--------
+[verse]
+'git ls-remote' [--heads] [--tags] [--refs] [--upload-pack=<exec>]
+	      [-q | --quiet] [--exit-code] [--get-url] [--sort=<key>]
+	      [--symref] [<repository> [<refs>...]]
+
+DESCRIPTION
+-----------
+Displays references available in a remote repository along with the associated
+commit IDs.
+
+
+OPTIONS
+-------
+-h::
+--heads::
+-t::
+--tags::
+	Limit to only refs/heads and refs/tags, respectively.
+	These options are _not_ mutually exclusive; when given
+	both, references stored in refs/heads and refs/tags are
+	displayed.
+
+--refs::
+	Do not show peeled tags or pseudorefs like `HEAD` in the output.
+
+-q::
+--quiet::
+	Do not print remote URL to stderr.
+
+--upload-pack=<exec>::
+	Specify the full path of 'git-upload-pack' on the remote
+	host. This allows listing references from repositories accessed via
+	SSH and where the SSH daemon does not use the PATH configured by the
+	user.
+
+--exit-code::
+	Exit with status "2" when no matching refs are found in the remote
+	repository. Usually the command exits with status "0" to indicate
+	it successfully talked with the remote repository, whether it
+	found any matching refs.
+
+--get-url::
+	Expand the URL of the given remote repository taking into account any
+	"url.<base>.insteadOf" config setting (See linkgit:git-config[1]) and
+	exit without talking to the remote.
+
+--symref::
+	In addition to the object pointed by it, show the underlying
+	ref pointed by it when showing a symbolic ref.  Currently,
+	upload-pack only shows the symref HEAD, so it will be the only
+	one shown by ls-remote.
+
+--sort=<key>::
+	Sort based on the key given. Prefix `-` to sort in descending order
+	of the value. Supports "version:refname" or "v:refname" (tag names
+	are treated as versions). The "version:refname" sort order can also
+	be affected by the "versionsort.suffix" configuration variable.
+	See linkgit:git-for-each-ref[1] for more sort options, but be aware
+	keys like `committerdate` that require access to the objects
+	themselves will not work for refs whose objects have not yet been
+	fetched from the remote, and will give a `missing object` error.
+
+-o <option>::
+--server-option=<option>::
+	Transmit the given string to the server when communicating using
+	protocol version 2.  The given string must not contain a NUL or LF
+	character.
+	When multiple `--server-option=<option>` are given, they are all
+	sent to the other side in the order listed on the command line.
+
+<repository>::
+	The "remote" repository to query.  This parameter can be
+	either a URL or the name of a remote (see the GIT URLS and
+	REMOTES sections of linkgit:git-fetch[1]).
+
+<refs>...::
+	When unspecified, all references, after filtering done
+	with --heads and --tags, are shown.  When <refs>... are
+	specified, only references matching the given patterns
+	are displayed.
+
