+Default usage
+
+You may either select files via the file dialog picker, or, drop
+the files onto the "dropzone".
+
+```jsx
+<FilePicker id="le-picker-single" title="Attach Files" />
+```
+
+Multiple
+
+```jsx
+<FilePicker id="le-picker-multi" title="Attach Multiple Files" multiple='multiple' />
+```
+
+The `receiveFilesChanged` prop allows you to receive notifications when
+the _FileList_ has changed. (see
+[File API](https://developer.mozilla.org/en-US/docs/Web/API/File_and_Directory_Entries_API))
+You can then iteract with these files using the [File API](https://developer.mozilla.org/en-US/docs/Web/API/FileReader/readAsDataURL)
+per file. For example, you may wish to do something like
+`FileReader.readAsDataURL(someFile)` before uploading to a server endpoint.
+
+Interact with the following example component and view the console output.
+
+```jsx
+const callback = filelist => { filelist.forEach(file => console.log('file: ', file)) }
+<FilePicker receiveFilesChanged={callback}  id="le-picker-notify" title="Attach" multiple='multiple' />
+```
+
+Errors
+
+Pass a `validator` function that verifies each of the files and returns an
+error message. The component will then take care of displaying these returned
+errors properly. To see this, pick a file greater then 10MB:
+
+```jsx
+const fileSizeError = 'The file size cannot exceed 10MB.';
+const validateFileSize = (files) => {
+  const max = 10240000;
+  const errors = files.reduce((acc, file) => {
+    if (file.size > max) {
+      acc.push(`${file.name} too big. ${fileSizeError}`);
+    }
+    return acc;
+  }, []);
+  return errors.join(' ');
+}
+<FilePicker validator={validateFileSize} id="validator-example" title="Attach Files" />
+```
