+=============================
+Intercom.io -- Real-time tracking
+=============================
+
+Intercom.io_ is an easy way to implement real-chat and individual
+support for a website
+
+.. _Intercom.io: http://www.intercom.io/
+
+
+.. intercom-installation:
+
+Installation
+============
+
+To start using the Intercom.io 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 Intercom.io 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:`intercom-configuration`.
+
+The Intercom.io Javascript code is inserted into templates using a
+template tag.  Load the :mod:`intercom` template tag library and
+insert the :ttag:`intercom` 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 body::
+
+    {% load intercom %}
+    <html>
+    <head></head>
+    <body>
+    <!-- Your page -->
+    {% intercom %}
+    </body>
+    </html>
+    ...
+
+
+.. _intercom-configuration:
+
+Configuration
+=============
+
+Before you can use the Intercom.io integration, you must first set your
+app id.
+
+
+.. _intercom-site-id:
+
+Setting the app id
+--------------------------
+
+Intercom.io gives you a unique app id, and the :ttag:`intercom`
+tag will include it in the rendered Javascript code.  You can find your
+app id by clicking the *Tracking Code* link when logged into
+the on the intercom.io website.  A page will display containing
+HTML code looking like this::
+
+    <script id="IntercomSettingsScriptTag">
+        window.intercomSettings = { name: "Jill Doe", email: "jill@example.com", created_at: 1234567890, app_id: "XXXXXXXXXXXXXXXXXXXXXXX" };
+    </script>
+    <script>(function(){var w=window;var ic=w.Intercom;if(typeof ic==="function"){ic('reattach_activator');ic('update',intercomSettings);}else{var d=document;var i=function(){i.c(arguments)};i.q=[];i.c=function(args){i.q.push(args)};w.Intercom=i;function l(){var s=d.createElement('script');s.type='text/javascript';s.async=true;s.src='https://static.intercomcdn.com/intercom.v1.js';var x=d.getElementsByTagName('script')[0];x.parentNode.insertBefore(s,x);}if(w.attachEvent){w.attachEvent('onload',l);}else{w.addEventListener('load',l,false);}}})()</script>
+
+The code ``XXXXXXXXXXXXXXXXXXXXXXX`` is your app id.  Set
+:const:`INTERCOM_APP_ID` in the project :file:`settings.py`
+file::
+
+    INTERCOM_APP_ID = 'XXXXXXXXXXXXXXXXXXXXXXX'
+
+If you do not set an app id, the Javascript code will not be
+rendered.
+
+
+Custom data
+-----------
+
+As described in the Intercom documentation on `custom visitor data`_,
+the data that is tracked by Intercom can be customized.  Using template
+context variables, you can let the :ttag:`intercom` tag pass custom data
+to Intercom automatically.  You can set the context variables in your view
+when your render a template containing the tracking code::
+
+    context = RequestContext({'intercom_cart_value': cart.total_price})
+    return some_template.render(context)
+
+For some data, it is annoying to do this for every view, so you may want
+to set variables in a context processor that you add to the
+:data:`TEMPLATE_CONTEXT_PROCESSORS` list in :file:`settings.py`::
+
+    from django.utils.hashcompat import md5_constructor as md5
+
+    GRAVATAR_URL = 'http://www.gravatar.com/avatar/'
+
+    def intercom_custom_data(request):
+        try:
+            email = request.user.email
+        except AttributeError:
+            return {}
+        email_hash = md5(email).hexdigest()
+        avatar_url = "%s%s" % (GRAVATAR_URL, email_hash)
+        return {'intercom_avatar': avatar_url}
+
+Just remember that if you set the same context variable in the
+:class:`~django.template.context.RequestContext` constructor and in a
+context processor, the latter clobbers the former.
+
+Standard variables that will be displayed in the Intercom live visitor
+data are listed in the table below, but you can define any ``intercom_*``
+variable you like and have that detail passed from within the visitor
+live stream data when viewing Intercom.
+
+====================  ===========================================
+Context variable       Description
+====================  ===========================================
+``intercom_name``       The visitor's full name.
+--------------------  -------------------------------------------
+``intercom_email``      The visitor's email address.
+--------------------  -------------------------------------------
+``created_at``          The date the visitor created an account
+====================  ===========================================
+
+
+.. _`custom visitor data`: http://docs.intercom.io/custom-data/adding-custom-data
+
+
+Identifying authenticated users
+-------------------------------
+
+If you have not set the ``intercom_name`` or ``intercom_email`` variables
+explicitly, the username and email address of an authenticated user are
+passed to Intercom automatically.  See :ref:`identifying-visitors`.
+
+.. _intercom-internal-ips:
+
+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:`ANALYTICAL_INTERNAL_IPS` setting
+(which is :const:`INTERNAL_IPS` by default,) the tracking code is 
+commented out. See :ref:`identifying-visitors` for important information
+about detecting the visitor IP address.
