 A developer should use the following steps to update the version ``X.Y.Z``
 of CastXML associated with the current CastXML python distributions.

 Available CastXML archives can be found `here <https://data.kitware.com/#folder/57b5de948d777f10f2696370>`_.
 
+First, build the artifacts which will be made available for download.
+
+Update CastXML files
+--------------------
+
+Using the `CastXMLSuperbuild <https://github.com/CastXML/CastXMLSuperbuild>`_
+repository, create a merge request which will use CI to automatically generate
+the appropriate binary files for the new version.  The version selection is
+controlled by the ``CastXML_GIT_TAG`` variable.
+
+If necessary, update the ``LLVM`` and ``clang`` versions.  Both objects have
+a ``<>_version`` and a ``<>_md5`` variable which need to be be updated at the
+same time.
+
+Once the CI has finished, view the "Details" of each task.  Follow the links
+to view and download the archive files created by each task. After download,
+extract the contents of the associated archive file.  The content of each ZIP
+file will be uploaded in the next step.
+
+Upload files to data.kitware.com
+--------------------------------
+
+To upload the files generated in the previous step, first create the folder for
+the new version of CastXML within the CastXML archive.  This can be done, after
+signing in to the instance, by clicking on the folder button in the upper right
+corner.
+
+**Note**: If the only option in the menu is *Download folder*, create an issue
+in this repository asking for write permission to this folder.
+
+Create a folder with the same name as the version of ``CastXML_GIT_TAG`` and
+upload the files from the previous step.
