+By default, Exif, IPTC and XMP tags are grouped together. This means that if
+e.g. `Orientation` exists in both Exif and XMP, the first value (Exif) will be
+overwritten by the second (XMP). If you need to separate between these values,
+pass in an options object with the property `expanded` set to `true`:
+
+```javascript
+const tags = ExifReader.load(fileBuffer, {expanded: true});
+```
+
+Notes
+-----
+
+Some XMP tags have processed values as descriptions. That means that e.g. an
+`Orientation` value of `3` will have `Rotate 180` in the `description` property.
+If you would like more XMP tags to have a processed description, please file an
+issue or do a pull request.
