-    This extension enables DuckDB to connect to Microsoft Fabric OneLake workspaces and lakehouses, allowing users to query data stored in OneLake directly from DuckDB. 
-    It supports authentication via service principals or credential chains (e.g., Azure CLI) and provides seamless integration with OneLake's data storage capabilities.
-    For detailed setup and usage instructions, visit the [extension repository](https://github.com/datumnova/duckdb_onelake).
+    This extension enables DuckDB to connect to Microsoft Fabric OneLake workspaces and lakehouses, allowing users to query and modify data stored in OneLake directly from DuckDB. 
+    It supports authentication via service principals, credential chains (e.g., Azure CLI), or environment tokens and provides seamless integration with OneLake's data storage capabilities.
     
-    Current limitations:
-    - Only read access is supported; write operations are not implemented.
+    Key Features:
+    - Read support for both Delta and Iceberg tables.
+    - Full write support for Delta tables including CREATE TABLE, INSERT, UPDATE, DELETE, and DROP.
+    - Configurable write modes (append, overwrite) and schema evolution.
+    - ALTER TABLE support is planned for future releases.
