+It will show the branch-name, or the commit hash if in detached head state.

+unmerged files (conflicts), changed files, untracked files and stashed files
+if that number is greater than zero.
+
+:param bool use_dash_c:
+    Call git with ``-C``, which is more performant and accurate, but requires git 1.8.5 or higher.
+    Otherwise it will traverse the current working directory up towards the root until it finds a ``.git`` directory, then use ``--git-dir`` and ``--work-tree``.
+    True by default.
+
+:param bool show_tag:
+    Show tag description. Valid options are``contains``, ``last``, ``annotated`` and ``exact``. A value of True behaves the same as ``exact``, which only displays a tag when it's assigned to the currently checked-out revision.
+    False by default, because it needs to execute git an additional time.
+
+:param dict formats:
+    A string-to-string dictionary for customizing Git status formats. Valid keys include ``branch``, ``tag``, ``ahead``, ``behind``, ``staged``, ``unmerged``, ``changes``, ``untracked``, and ``stashed``.
+    Empty dictionary by default, which means the default formats are used.
+
+:param detached_head_style:
+    Display style when in detached HEAD state. Valid values are ``revision``, which shows the current revision id, and ``ref``, which shows the closest reachable ref object.
+    The default is ``revision``.
+
+:param untracked_not_dirty:
+    Untracked files alone will not mark the git branch status as dirty.
+    False by default.
+
+Divider highlight group used: ``gitstatus:divider``.
+
+Highlight groups used: ``gitstatus_branch_detached``, ``gitstatus_branch_dirty``, ``gitstatus_branch_clean``, ``gitstatus_branch``, ``gitstatus_tag``, ``gitstatus_behind``, ``gitstatus_ahead``, ``gitstatus_staged``, ``gitstatus_unmerged``, ``gitstatus_changed``, ``gitstatus_untracked``, ``gitstatus_stashed``, ``gitstatus``.
