+=========================
+External Database Sources
+=========================
+
+This module allows you to define connections to foreign databases using ODBC,
+Oracle Client or SQLAlchemy.
+
+Installation
+============
+
+No installation required.
+
+Configuration
+=============
+
+Database sources can be configured in Settings > Configuration -> Data sources.
+
+Depending on the database, you need:
+
+* to install unixodbc and python-pyodbc packages to use ODBC connections.
+* to install FreeTDS driver (tdsodbc package) and configure it through ODBC toconnect to Microsoft SQL Server.
+* to install and configure Oracle Instant Client and cx_Oracle python library to connect to Oracle.
+
+
+Usage
+=====
+
+To use this module:
+
+* Go to Settings > Database Structure > Database Sources
+* Click on Create to enter the following information:
+
+* Datasource name 
+* Pasword
+* Connector: Choose the database to which you want to connect
+* Connection string : Specify how to connect to database
