+Python support within ROCm Systems Profiler
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ROCm Systems Profiler supports profiling Python code via the ``ROCPROFSYS_USE_PYTHON`` CMake option.
+Python support is enabled via the ``ROCPROFSYS_USE_PYTHON`` and the
+``ROCPROFSYS_PYTHON_VERSIONS="<MAJOR>.<MINOR>`` CMake options.
+Alternatively, to build multiple Python versions, use
+``ROCPROFSYS_PYTHON_VERSIONS="<MAJOR>.<MINOR>;[<MAJOR>.<MINOR>]"``,
+and ``ROCPROFSYS_PYTHON_ROOT_DIRS="/path/to/version;[/path/to/version]"`` instead of just ``ROCPROFSYS_PYTHON_VERSIONS``.
+When building multiple Python versions, the length of the ``ROCPROFSYS_PYTHON_VERSIONS``
+and ``ROCPROFSYS_PYTHON_ROOT_DIRS`` lists must
+be the same size.
