+==========================
+The "local flavor" add-ons
+==========================
+
+Django comes with assorted pieces of code that are useful only for a particular
+country or culture.  These pieces of code are organized as a set of
+subpackages, named using `ISO 3166 country codes`_.
+
+.. _ISO 3166 country codes: http://www.iso.org/iso/country_codes/iso_3166_code_lists/english_country_names_and_code_elements.htm
+
+Most of the ``localflavor`` add-ons are localized form components deriving from
+the newforms_ framework.  To use one of these localized components, just import
+the relevant subpackage.  For example, a form with a field for French telephone
+numbers is created like so::
+
+    from django import newforms as forms
+    from django.contrib.localflavor import fr
+
+    class MyForm(forms.Form):
+        my_french_phone_no = fr.forms.FRPhoneNumberField()
+
+Countries currently supported by ``localflavor`` are:
+
+* Argentina_
+* Australia_
+* Brazil_
+* Canada_
+* Chile_
+* Finland_
+* France_
+* Germany_
+* Holland_
+* Iceland_
+* India_
+* Italy_
+* Japan_
+* Mexico_
+* Norway_
+* Peru_
+* Poland_
+* Slovakia_
+* `South Africa`_
+* Spain_
+* Switzerland_
+* `United Kingdom`_
+* `United States of America`_
+
+.. _Argentina: `Argentina (django.contrib.localflavor.ar)`_
+.. _Australia: `Australia (django.contrib.localflavor.au)`_
+.. _Brazil: `Brazil (django.contrib.localflavor.br)`_
+.. _Canada: `Canada (django.contrib.localflavor.ca)`_
+.. _Chile: `Chile (django.contrib.localflavor.cl)`_
+.. _Finland: `Finland (django.contrib.localflavor.fi)`_
+.. _France: `France (django.contrib.localflavor.fr)`_
+.. _Germany: `Germany (django.contrib.localflavor.de)`_
+.. _Holland: `Holland (django.contrib.localflavor.nl)`_
+.. _Iceland: `Iceland (django.contrib.localflavor.is\_)`_
+.. _India: `India (django.contrib.localflavor.in\_)`_
+.. _Italy: `Italy (django.contrib.localflavor.it)`_
+.. _Japan: `Japan (django.contrib.localflavor.jp)`_
+.. _Mexico: `Mexico (django.contrib.localflavor.mx)`_
+.. _Norway: `Norway (django.contrib.localflavor.no)`_
+.. _Peru: `Peru (django.contrib.localflavor.pe)`_
+.. _Poland: `Poland (django.contrib.localflavor.pl)`_
+.. _Slovakia: `Slovakia (django.contrib.localflavor.sk)`_
+.. _South Africa: `South Africa (django.contrib.localflavor.za)`_
+.. _Spain: `Spain (django.contrib.localflavor.es)`_
+.. _Switzerland: `Switzerland (django.contrib.localflavor.ch)`_
+.. _United Kingdom: `United Kingdom (django.contrib.localflavor.uk)`_
+.. _United States of America: `United States of America (django.contrib.localflavor.us)`_
+
+The ``localflavor`` add-on also includes the ``generic`` subpackage, containing
+useful code that is not specific to one particular country or culture.
+Currently, it defines date and date & time input fields based on those from
+newforms_, but with non-US default formats.  Here's an example of how to use
+them::
+
+    from django import newforms as forms
+    from django.contrib.localflavor import generic
+
+    class MyForm(forms.Form):
+        my_date_field = generic.forms.DateField()
+
+.. _newforms: ../newforms/
+
+
+.. admonition:: Adding a Flavor
+
+   We'd love to add more of these to Django, so please create a ticket for
+   anything that you've found useful. Please use unicode objects
+   (``u'mystring'``) for strings, rather than setting the encoding in the file
+   (see any of the existing flavors for examples).
