-### TensorFlow operations
-
-MLIR operations can represent arbitrary TensorFlow operations with a reversible
-mapping. Switch and merge nodes are represented with the MLIR control flow
-graph. TensorFlow dataflow operations are mapped over to MLIR operations whose
-name gets a "tf." prefix.
-
-The normal dtypes supported by TensorFlow are mapped onto a Tensor type with an
-unknown rank. The resource and variant dtypes are mapped onto our resource and
-variant type specifically (TODO: Specify this). Attributes get mapped over
-directly, with type attributes represented as strings.
-
-Examples:
-
-```mlir {.mlir}
-// TensorFlow Add operation.
-%a = "tf.Add"(%b, %c)
-  : (tensor<*xf32>,tensor<*xf32>) -> tensor<*xf32>
-
-// TensorFlow Add operation with partially inferred shapes.
-%d = "tf.Add"(%e, %f)
-  : (tensor<?x42x?xf32>,tensor<?x42x?xf32>) -> tensor<?x42x?xf32>
-
-// TensorFlow Conv2d operation.
-%y = "tf.Conv2d"(%input, %filter)
