+Connecting with SSL
+^^^^^^^^^^^^^^^^^^^
+
+Thanks to a community contribution, SSL Cert support has been added: `SSL Support  <https://github.com/ElasticHQ/elasticsearch-HQ/issues/376>`_.
+
+Enable SSL Cert support by starting HQ as so:
+
+``python -m application --enable-ssl --ca-certs /path/to/your/ca.crt``
+

 Database
 ^^^^^^^^
 
 ElasticHQ ships with SQLLite integration to store clusters you have connected to and other meta information. This database is kept under the root directory as ``elastichq.db``.
 
 .. note:: In the event you want to start with a clean slate, simply delete the ``elastichq.db`` file. ElasticHQ will recreate it at next startup.
 
+External Configuration
+^^^^^^^^^^^^^^^^^^^^^^
+
+External configuration files are supported for those wanting to preserve their user-specified settings between upgrades.
+
+On startup, HQ checks the following locations for a file named ``settings.json``:
+
+* `/etc/elastic-hq/settings.json`
+* `~/settings.json`
+* CURRENT WORKING DIRECTORY + ``/settings.json``
+* CURRENT WORKING DIRECTORY + ``/elastichq/settings.json``
+* CURRENT WORKING DIRECTORY + ``/config/settings.json``
+
+Current supported parameters are:
+
+    =========================== ====================================================================
+    Key                         Definition
+    =========================== ====================================================================
+    ``SQLALCHEMY_DATABASE_URI`` Location and Name of ElasticHQ database file.
+    =========================== ====================================================================
+
+The settings file should be in standard JSON:

+.. code-block:: json
+
+    {
+      "SQLALCHEMY_DATABASE_URI" :  "sqlite:////SOME/PATH/TO/DB_NAME.db"
