#36 control the vertical position

README.md

@@ -150,6 +150,24 @@ You can copy-paste these lines of code for a quick test:
 <button onclick="window.plugins.toast.show('Hello there!', 'long', 'center', function(a){console.log('toast success: ' + a)}, function(b){alert('toast error: ' + b)})">Toast show long center</button>
 ```
 
+#### Tweaking the vertical position (iOS only for now)
+Since 2.1.0 you can add pixels to move the toast up or down.
+Note that `showWithOptions` can be used instead of the functions above, but it's not useful unless you want to pass `addPixelsY`.
+```js
+function showTop() {
+  window.plugins.toast.showWithOptions(
+    {
+      message: "hey there",
+      duration: "short",
+      position: "bottom",
+      addPixelsY: -40  // added a negative value to move it up a bit (default 0)
+    },
+    onSuccess, // optional
+    onError    // optional
+  );
+}
+```
