+# About this fork
+**NOTE:** [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.
+Report any issues to https://github.com/protobi/js-xlsx/issues.
+
+For those contributing to this fork:
+* `master` is the main branch, which follows the original repo to enable a future pull request.
+* `beta` branch is published to npm and bower to make this fork available for use.

+## Cell Styles
+
+Cell styles are specified by a style object that roughly parallels the OpenXML structure.  The style object has five
+top-level attributes: `fill`, `font`, `numFmt`, `alignment`, and `border`.
+
+
+| Style Attribute | Sub Attributes | Values |
+| :-------------- | :------------- | :------------- |
+| fill            | patternType    |  `"solid"` or `"none"`

+|                 | diagonalDown   | `true` or `false`
+
+**COLOR_SPEC**: Colors for `fill`, `font`, and `border` are specified as objects, either:
+* `{ auto: 1}` specifying automatic values
+* `{ rgb: "FFFFAA00" }` specifying a hex ARGB value
+* `{ theme: "1", tint: "-0.25"}` specifying an integer index to a theme color and a tint value (default 0)
+* `{ indexed: 64}` default value for `fill.bgColor`
+
+**BORDER_STYLE**: Border style is a string value which may take on one of the following values:
+ * `thin`
+ * `medium`
+ * `thick`
+ * `dotted`
+ * `hair`
+ * `dashed`
+ * `mediumDashed`
+ * `dashDot`
+ * `mediumDashDot`
+ * `dashDotDot`
+ * `mediumDashDotDot`
+ * `slantDashDot`
+
+
+Borders for merged areas are specified for each cell within the merged area.  So to apply a box border to a merged area of 3x3 cells, border styles would need to be specified for eight different cells:
+* left borders for the three cells on the left,
+* right borders for the cells on the right
+* top borders for the cells on the top
+* bottom borders for the cells on the left
+
