+Only the first two options `bcid` and `text` are required.  The other bwip-js
+specific options are:
+
+- `scaleX` : The x-axis scaling factor.  Must be an integer > 0.  Default is 2.
+- `scaleY` : The y-axis scaling factor.  Must be an integer > 0.  Default is `scaleX`.
+- `scale` : Sets both the x-axis and y-axis scaling factors.  Must be an integer > 0.
+
+- `rotate` : Allows rotating the image to one of the four orthogonal orientations.  A string value.  Must be one of:
+
+    * `"N"` : Normal (not rotated).  The default.
+    * `"R"` : Clockwise (right) 90 degree rotation.
+    * `"L"` : Counter-clockwise (left) 90 degree rotation.
+    * `"I"` : Inverted 180 degree rotation.
+
+- `monochrome` : Sets the human-readable text to render in monochrome.  Boolean `true` or `false`.  Default is `false` which renders 256-level gray-scale anti-aliased text.
 
 You will need to consult the
 [BWIPP documentation](https://github.com/bwipp/postscriptbarcode/wiki)
 to determine what options are available for each barcode type.
