+# `hudi-flink-bundle` module
+
+This module packages the Hudi Flink bundle for reading and writing Hudi tables
with Flink.
+
+## Lance dependencies
+
+The Hudi Flink bundle does not include Lance runtime dependencies. To use
Lance with Hudi,
+ensure that the Flink runtime includes the following dependencies and their
required transitive
+dependencies. Use versions compatible with the dependencies of your Hudi
version; see its
+[root POM](../../pom.xml) for the Lance and Arrow versions.
