 # Iceberg Pipeline Connector
 
-The Iceberg Pipeline Connector functions as a *Data Sink* for data pipelines, enabling data writes to Apache Iceberg tables[Iceberg](https://iceberg.apache.org). This document explains how to configure the connector.
+The Iceberg Pipeline Connector functions as a *Data Sink* for data pipelines, enabling data writes to [Apache Iceberg](https://iceberg.apache.org) tables. This document explains how to configure the connector.
 
 ## Key Capabilities
-* Automatic Table Creation
-Creates Iceberg tables dynamically when they do not exist
-* Schema Synchronization
-Propagates schema changes (e.g., column additions) from source systems to Iceberg
-* Data Replication
-Supports both batch and streaming data synchronization

 Usage Notes
 --------
 
-* Only support Iceberg primary key table, so the source table must have primary keys.
+* The source table must have a primary key. Tables with no primary key are not supported.
 
-* Not support exactly-once. The connector uses at-least-once + primary key table for idempotent writing.
+* Exactly-once semantics are not supported. The connector uses at-least-once + the table's primary key for idempotent writing.
