+### Importing data into your deployment
+
+There are several ways to import data into your Data Warehouse for ClickHouse® deployment, depending on how your data is stored:
+
+- Using the `s3` table function: directly read data from an Amazon S3 bucket by specifying the bucket URL, the file format, and data structure.
+
+- Using the `s3` Storage Engine: create a table that points to your S3 data, then insert data from the S3 table into your target table.
+
+- Using `clickhouse-client`: execute an INSERT query to populate a table by specifying the bucket URL and the file format.
