+Local themes
+************
+
+From the user point of view local themes are the regular themes with a specific
+scope where they are applied (i.e. specific vim window or specific kind of
+prompt). Used themes are defined in :ref:`local_themes key
+<config-ext-local_themes>`.
+
+Vim local themes
+================
+
+Vim is the only available extension that has a wide variaty of options for local
+themes. It is the only extension where local theme key refers to a function as
+described in :ref:`local_themes value documentation <config-ext-local_themes>`.
+
+This function always takes a single value named ``matcher_info`` which is the
+same dictionary as :ref:`segment_info dictionary <dev-segment_info-vim>`. Unlike
+segments it takes this single argument as a *positional* argument, not as
+a keyword one.
+
+Matcher function should return a boolean value: ``True`` if theme applies for
+the given ``matcher_info`` dictionary or ``False`` if it is not. When one of the
+matcher functions returns ``True`` powerline takes the corresponding theme at
+uses it for the given window. Matchers are not tested in any particular order.
+
+In addition to :ref:`local_themes configuration key <config-ext-local_themes>`
+developer of some plugin which wishes to support powerline without including his
+code in powerline tree may use
+:py:meth:`powerline.vim.VimPowerline.add_local_theme` method. It accepts two
+arguments: matcher name (same as in :ref:`local_themes
+<config-ext-local_themes>`) and dictionary with theme. This dictionary is merged
+with :ref:`top theme <config-ext-top_theme>` and
+:file:`powerline/themes/vim/__main__.json`. Note that if user already specified
+the matcher in his configuration file ``KeyError`` is raised.
+
+Other local themes
+==================
+
+Except for Vim only IPython and shells have local themes. Unlike Vim these
+themes are names with no special meaning (they do not refer to or cause loading
+of any Python functions):
