-# Python-oracledb  Examples
+# Python Examples
 
-This directory contains samples for python-oracledb, the Python driver for
-Oracle Database.
+This directory contains Oracle Database Python examples for:
 
-1.  The schemas and SQL objects that are referenced in the samples can be
-    created by running the Python script
-    [create_schema.py](https://github.com/oracle-samples/oracle-db-examples/blob/main/python/create_schema.py). The
-    script requires SYSDBA privileges and will prompt for these credentials as
-    well as the names of the schemas and edition that will be created, unless a
-    number of environment variables are set as documented in the Python script
-    [sample_env.py](https://github.com/oracle-samples/oracle-db-examples/blob/main/python/sample_env.py). Run
-    the script using the following command:
-
-        python create_schema.py
-
-2.  Run a Python script, for example:
-
-        python query.py
-
-3.  After running python-oracledb samples, the schemas and SQL objects can be
-    dropped by running the Python script
-    [drop_schema.py](https://github.com/oracle-samples/oracle-db-examples/blob/main/python/drop_schema.py). The
-    script requires SYSDBA privileges and will prompt for these credentials as
-    well as the names of the schemas and edition that will be dropped, unless a
-    number of environment variables are set as documented in the Python script
-    [sample_env.py](https://github.com/oracle-samples/oracle-db-examples/blob/main/python/sample_env.py). Run
-    the script using the following command:
-
-        python drop_schema.py

-## About python-oracledb
-
-- Python-oracledb is the new name for Oracle's popular Python cx_Oracle driver
-  for Oracle Database.
-
-- Python-oracledb 1.0 is a new major release - the successor to cx_Oracle 8.3.
-
-- Python-oracledb is simple and small to install — under 15 MB (including
-  Python package dependencies): `pip install oracledb`
-
-- Python-oracledb is now a Thin driver by default - it connects directly to
-  Oracle Database without always needing Oracle Client libraries.
-
-- Python-oracledb has comprehensive functionality conforming to the Python
-  Database API v2.0 Specification, with many additions and just a couple of
-  exclusions.
-
-- A "Thick" mode can be optionally enabled by an application call. This mode
-  has similar functionality to cx_Oracle and supports Oracle Database features
-  that extend the Python DB API. To use this mode, the widely used and tested
-  Oracle Client libraries such as from Oracle Instant Client must be installed
-  separately.
-
-- Python-oracledb runs on many platforms including favorites like Linux, macOS
-  and Windows. It can also be used on platforms where Oracle Client libraries
-  are not available (such as Apple M1, Alpine Linux, or IoT devices), or where
-  the client libraries are not easily installed (such as some cloud
-  environments).
