+Importing CSV from AWS S3 into Exasol
+-------------------------------------
+This example demonstrates how to import a CSV file from AWS S3 into Exasol using the `IMPORT FROM CSV` command.
+
+Step 1: Create a Virtual Schema Connection
+------------------------------------------
+
+Establish a connection to your AWS S3 bucket using your AWS credentials:
+
+.. code-block:: sql
+
+    CREATE CONNECTION S3_MY_BUCKET
+    TO 'http://<my_bucketname>.s3.<my_region>.amazonaws.com'
+    USER '<my_access_key>'
+    IDENTIFIED BY '<my_secret_key>';
+
+Step 2: Create a Table
+----------------------
+
+Define the structure of the target table where the data from the CSV file will be stored:
+
+.. code-block:: sql
+
+    CREATE TABLE sales_data (
+        order_id INT,
+        product_name VARCHAR(100),
+        quantity INT,
+        price DOUBLE
+    );
+
+Step 3: Import Data
+-------------------
+
+Execute the `IMPORT FROM CSV` command using the defined connection and specifying the details of the CSV file, such as its location, column separators, and encoding:
+
+.. code-block:: sql
+
+    IMPORT INTO sales_data
+    FROM CSV
+    AT S3_MY_BUCKET
+    FILE 'sales_2025/sales.csv'
+    COLUMN SEPARATOR = ';'
+    ROW SEPARATOR = 'CRLF'
+    COLUMN DELIMITER = '"'
+    ENCODING = 'UTF-8'
+    SKIP = 1;
+
+.. note::
+    Make sure to replace `my-access-key`, `my-secret-access`, `my-bucket-name` with your actual AWS S3 credentials.
+
+For more detailed information and additional options, refer to the Exasol documentation at: `Exasol Documentation <https://docs.exasol.com/db/latest/sql/import.htm>`.
