+=====================================
+Heap -- analytics and events tracking
+=====================================
+
+`Heap`_ automatically captures all user interactions on your site, from the moment of installation forward. 
+
+.. _`Heap`: https://heap.io/
+
+
+.. heap-installation:
+
+Installation
+============
+
+To start using the Heap 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.
+
+.. _heap-configuration:
+
+Configuration
+=============
+
+Before you can use the Heap integration, you must first get your
+Heap Tracker ID. If you don't have a Heap account yet,
+`sign up`_ to get your Tracker ID.
+
+.. _`sign up`: https://heap.io/
+
+
+.. _heap-tracker-id:
+
+Setting the Tracker ID
+----------------------
+
+Heap gives you a unique ID. You can find this ID on the Projects page
+of your Heap account. Set :const:`HEAP_TRACKER_ID` in the project
+:file:`settings.py` file::
+
+    HEAP_TRACKER_ID = 'XXXXXXXX'
+
+If you do not set an Tracker ID, the tracking code will not be
+rendered.
+
+The tracking code will be added just before the closing head tag.
+
+
+.. _heap-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.
