 ### YAML Based Named Structured Ops
 
 Linalg provides a declarative generation tool (`mlir-linalg-ods-yaml-gen`) to
-automatically produce named ops from a YAML-based op description format
-intended to capture the structure of the named ops and be generated from a
-higher level "mathy" DSL syntax. This facility is currently in flight and is
-intended to subsume the above when ready. See the C++ class to YAML mapping
-traits in `mlir-mlinalg-ods-yaml-gen.cpp` as the source of truth for the schema.

 Most of the above documentation roughly applies to this path and will be ported
 as migration continues.
