+
 Get the ArrayBuffer out of a DataView, robustly.
+
+This will work in node <= 0.10 and < 0.11.4, where there's no prototype accessor, only a nonconfigurable own property.
+It will also work in modern engines where `DataView.prototype.buffer` has been deleted after this module has loaded.
+
+## Example
+
+```js
+const dataViewBuffer = require('data-view-buffer');
+const assert = require('assert');
+
+const ab = new ArrayBuffer(0);
+const dv = new DataView(ab);
+assert.equal(dataViewBuffer(dv), ab);
+```
+
+## Tests
+Simply clone the repo, `npm install`, and run `npm test`
