+## About this fork
 [This project](https://github.com/SheetJS/js-xlsx/tree/beta) is a fork of the original (and awesome) [SheetJS/xlsx](https://github.com/SheetJS/js-xlsx) project.
 It is extended to enable cell formats to be read from and written to .xlsx workbooks.
 The intent is to provide a temporary means of using these features in practice, and ultimately to merge this into the primary project.
