+# Overview
+
+The **Oracle Virtual Schema** provides an abstraction layer that makes an external [Oracle database](https://www.oracle.com/database/) accessible from an Exasol database through regular SQL commands. The contents of the external Oracle database are mapped to virtual tables which look like and can be queried as any regular Exasol table.
+
+If you want to set up a Virtual Schema for a different database system, please head over to the [Virtual Schemas Repository][virtual-schemas].
+
+## Features
+
+* Access an Oracle database in read only mode from an Exasol database, using a Virtual Schema.
+
+## Table of Contents
+
+### Information for Users
+
+* [Virtual Schemas User Guide][virtual-schemas-user-guide]
+* [Oracle Dialect User Guide](doc/user_guide/oracle_user_guide.md)
+* [Changelog](doc/changes/changelog.md)
