+# Document history for slide show
+
+This slide show was originally written in LibreOffice Present. It was converted to MicroSoft Power Point in March 2024. During that conversion, a few minor changes/clean-ups were made. But it's largely the same presentation.
+
+However, the conversion was entirely manual.  There is no automatic tracking between the two documents.  If changes are made to either (the PPTX or ODP), they won't automatically be made to the other.
+
+The PDF was rendered by LibreOffice.
