 HIPCC documentation
 ******************************************
 
-``hipcc`` is a compiler driver utility that will call clang or nvcc, depending on target, and pass the appropriate include and library options for the target compiler and HIP infrastructure.
+.. note::
+  ROCm provides and supports multiple compilers as described in `ROCm compiler reference <https://rocm.docs.amd.com/projects/llvm-project/en/latest/reference/rocmcc.html>`_.
 
-There are both C++ and Perl executable versions of the ``hipcc`` and ``hipconfig`` compiler driver utilities provided. By default the C++ version is used when ``hipcc`` is run.
