+# Pandas Cheat Sheet
+
+The Pandas Cheat Sheet was created using Microsoft Powerpoint 2013.
+To create the PDF version, within Powerpoint, simply do a "Save As"
+and pick "PDF" as the format.
+
+This cheat sheet, originally written by Irv Lustig, [Princeton Consultants](https://www.princetonoptimization.com/), was inspired by the [RStudio Data Wrangling Cheatsheet](https://www.rstudio.com/wp-content/uploads/2015/02/data-wrangling-cheatsheet.pdf).
