-- Local installation on your machine
+ESMValTool may be run on multiple platforms, including local machines and
+large compute clusters; the benefit of using a compute cluster is that most often than not,
+it will host an ESGF node where CMIP data is locally stored on disk and accessible directly by the tool;
+in the same manner, observational (OBS) data will be found centrally stored as well. Here are a few options
