+// This file implements conversions between:
+//    named <--> category (elementwise, contraction, ..) <--> generic ops.
+//
+// For example, a named op such `linalg.add` can also be re-written as an
+// equivalent category op `linalg.elementwise` and also as a `linalg.generic`.
+//
+// Generic is a bigger set than named ops and so not all generics can be
+// converted to single category-op or named-op. Similarly, category-ops
+// are bigger in representational possiblities than named ops e.g.

Maybe not have the same docs as in the table-gen file here?
