+rocSPARSE backend
+----------------
+
+Currently known limitations:
+
+- Using ``spmv`` with a ``type_view`` other than ``matrix_descr::general`` will
+  throw a ``oneapi::math::unimplemented`` exception.
+- The COO format requires the indices to be sorted by row then by column. See
+  the `rocSPARSE COO documentation
+  <https://rocm.docs.amd.com/projects/rocSPARSE/en/latest/how-to/basics.html#coo-storage-format>`_.
+  Sparse operations using matrices with the COO format without the property
+  ``matrix_property::sorted`` will throw a ``oneapi::math::unimplemented``
+  exception.
+- The CSR format requires the column indices to be sorted within each row. See
+  the `rocSPARSE CSR documentation
+  <https://rocm.docs.amd.com/projects/rocSPARSE/en/latest/how-to/basics.html#csr-storage-format>`_.
+  Sparse operations using matrices with the CSR format without the property
+  ``matrix_property::sorted`` will throw a ``oneapi::math::unimplemented``
+  exception.
+- The same sparse matrix handle cannot be reused for multiple operations
+  ``spmm``, ``spmv``, or ``spsv``. Doing so will throw a
+  ``oneapi::math::unimplemented`` exception. See `#332
+  <https://github.com/ROCm/rocSPARSE/issues/332>`_.
