 This package has been deployed on npm as [hed-validator](https://www.npmjs.com/package/hed-validator).
 
 To use the `hed-validator`, you must install the npm `hed-validator` package and add:
-`const hedValidator = require('hed-validator')` to your JavaScript program.
+`import hedValidator from 'hed-validator'` to your JavaScript program.
 
-Currently, only validation at the BIDS dataset level is supported as an external interface,
-because full HED-3G validation requires the entire events file and merged sidecars be available.

-`eventData` is an array of `BidsEventFile` objects created from BIDS `events.tsv` files,
-while `sidecarData` is an array of `BidsSidecar` objects created from BIDS JSON sidecars.
-`datasetDescriptionData` is a `BidsJsonFile` object representing the dataset's
-`dataset_description.json` file, and `dir` is the path to the dataset's root directory.
-
-The primary objects needed for HED validation can be found in
-[validator/bids/types.js](https://github.com/hed-standard/hed-javascript/blob/master/validator/bids/types.js).
