+
+## Configuration and Initialization
+
+### LanceDB Cloud
+
+For LanceDB Cloud, use the simplified builder API:
+
+```java
+import com.lancedb.lance.namespace.LanceRestNamespace;
+
+// If your DB url is db://example-db, then your database here is example-db
+LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
+    .apiKey("your_lancedb_cloud_api_key")
+    .database("your_database_name")
+    .build();
+```
+
+### LanceDB Enterprise
+
+For Enterprise deployments, use your VPC endpoint:
+
+```java
+LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
+    .apiKey("your_lancedb_enterprise_api_key")
+    .database("your-top-dir") // Your top level folder under your cloud bucket, e.g. s3://your-bucket/your-top-dir/
+    .hostOverride("http://<vpc_endpoint_dns_name>:80")
+    .build();
+```
