+Testing Elasticutils
+--------------------
+
+Testing elasticutils requires pyes_ and nose_. The easiest way to test is
+to set up a new virtualenv with those packages installed:
+
+::
+
+    mkvirtualenv elasticutils
+    workon elasticutils
+    pip install pyes
+    pip install nose
+
+Then, ``cd`` to the elasticutils base directory and run:
+
+::
+
+        nosetests -w tests/
+
+You may need to edit `es_settings.py` to change the value of ES_HOSTS to match
+the IP or port that elasticsearch is listening on.
