+# Titanium iOS 13+ Document Scanner
+
+Use the iOS 13+ `VisionKit` document scanner API in Appcelerator Titanium.
+
+## Requirements
+
+- [x] Titanium SDK 8.2.0+
+- [x] iOS 13+
+
+## Example
+
+```js
+var Scanner = require('ti.scanner');
+
+var win = Ti.UI.createWindow({
+    backgroundColor: '#fff'
+});
+
+var btn = Ti.UI.createButton({
+    title: 'Scan Document'
+});
+
+btn.addEventListener('click', function () {
+    Ti.Media.requestCameraPermissions(event => {
+        if (!event.success) {
+            alert('No camera permissions');
+            return;
+        }
+        Scanner.showScanner();
+    });
+});
+
+Scanner.addEventListener('cancel', function () {
+    Ti.API.warn('Cancelled …');
+});
+
+Scanner.addEventListener('error', function (event) {
+    Ti.API.error('Errored …');
+    Ti.API.error(event.error);
+});
+
+Scanner.addEventListener('success', function (event) {
+    Ti.API.warn('Succeeded …');
+    Ti.API.warn(event);
+
+    var win2 = Ti.UI.createWindow({
+          backgroundColor: '#333'
+    });
+
+    var image = Ti.UI.createImageView({
+          height: '70%',
+          image: Scanner.imageOfPageAtIndex(0) /* Or many images via "event.pageCount" */
+    });
+
+    win2.add(image);
+    win2.open();
