@ -172,6 +172,16 @@ two tags::
All tags live in the ``i18n`` tag library, so you need to specify
``{% load i18n %}`` in the head of your template to make use of them.
There are some places where you will encounter constant strings in your template code.
One is filter arguments, the other are normal string constants for tags. If you need to
translate those, you can use the ``_("....")`` syntax::
{% some_special_tag _("Page not found") value|yesno:_("yes,no") %}
In this case both the filter and the tag will see the already translated string, so they
don't need to be aware of translations. And both strings will be pulled out of the templates
for translation and stored in the .po files.
