+==================================
+Yandex.Metrica -- traffic analysis
+==================================
+
+`Yandex.Metrica`_ is an analytics tool like as google analytics.
+
+.. _`Yandex.Metrica`: http://metrica.yandex.com/
+
+
+.. yandex-metrica-installation:
+
+Installation
+============
+
+To start using the Yandex.Metrica integration, you must have installed the
+django-analytical package and have added the ``analytical`` application
+to :const:`INSTALLED_APPS` in your project :file:`settings.py` file.
+See :doc:`../install` for details.
+
+Next you need to add the Yandex.Metrica template tag to your templates. This
+step is only needed if you are not using the generic
+:ttag:`analytical.*` tags.  If you are, skip to
+:ref:`yandex-metrica-configuration`.
+
+The Yandex.Metrica counter code is inserted into templates using a template
+tag.  Load the :mod:`yandex_metrica` template tag library and insert the
+:ttag:`yandex_metrica` tag.  Because every page that you want to track must
+have the tag, it is useful to add it to your base template.  Insert
+the tag at the bottom of the HTML head::
+
+    {% load yandex_metrica %}
+    <html>
+    <head>
+    ...
+    {% yandex_metrica %}
+    </head>
+    ...
+
+
+.. _yandex-metrica-configuration:
+
+Configuration
+=============
+
+Before you can use the Yandex.Metrica integration, you must first set
+your website counter ID.
+
+
+.. _yandex-metrica-counter-id:
+
+Setting the counter ID
+----------------------
+
+Every website you track with Yandex.Metrica gets its own counter ID,
+and the :ttag:`yandex_metrica` tag will include it in the rendered
+Javascript code.  You can find the web counter ID on the overview page
+of your account.  Set :const:`YANDEX_METRICA_COUNTER_ID` in the
+project :file:`settings.py` file::
+
+    YANDEX_METRICA_COUNTER_ID = '12345678'
+
+If you do not set a counter ID, the counter code will not be rendered.
+
+You can set additional options to tune your counter:
+
+============================  =============  =============================================
+Constant                      Default Value  Description
+============================  =============  =============================================
+``YANDEX_METRICA_WEBVISOR``     False        Webvisor, scroll map, form analysis.
+``YANDEX_METRICA_TRACKHASH``    False        Hash tracking in the browser address bar.
+``YANDEX_METRICA_NOINDEX``      False        Stop automatic page indexing.
+``YANDEX_METRICA_ECOMMERCE``    False        Dispatch ecommerce data to Metrica.
+============================  =============  =============================================
+
+Internal IP addresses
+---------------------
+
+Usually you do not want to track clicks from your development or
+internal IP addresses.  By default, if the tags detect that the client
+comes from any address in the :const:`YANDEX_METRICA_INTERNAL_IPS` setting,
+the tracking code is commented out.  It takes the value of
+:const:`ANALYTICAL_INTERNAL_IPS` by default (which in turn is
+:const:`INTERNAL_IPS` by default).  See :ref:`identifying-visitors` for
+important information about detecting the visitor IP address.
