+
+A JupyterLab extension for rendering VirtualDOM using React
+
+![demo](http://g.recordit.co/EIwAIBsGBh.gif)
+
+## Prerequisites
+
+- JupyterLab ^0.27.0
+
+## Usage
+
+To render VDOM output in IPython:
+
+```python
+from IPython.display import display
+
+def VDOM(data={}):
+    bundle = {}
+    bundle['application/vdom.v1+json'] = data
+    display(bundle, raw=True)
+
+VDOM({
+    'tagName': 'div',
+    'attributes': {},
+    'children': [{
+        'tagName': 'h1',
+        'attributes': {},
+        'children': 'Our Incredibly Declarative Example',
+        'key': 0
+    }, {
+        'tagName': 'p',
+        'attributes': {},
+        'children': ['Can you believe we wrote this ', {
+            'tagName': 'b',
+            'attributes': {},
+            'children': 'in Python',
+            'key': 1
+        }, '?'],
+        'key': 1
+    }, {
+        'tagName': 'img',
+        'attributes': {
+            'src': 'https://media.giphy.com/media/xUPGcguWZHRC2HyBRS/giphy.gif'
+        },
+        'key': 2
+    }, {
+        'tagName': 'p',
+        'attributes': {},
+        'children': ['What will ', {
+            'tagName': 'b',
+            'attributes': {},
+            'children': 'you',
+            'key': 1
+        }, ' create next?'],
+        'key': 3
+    }]
+})
+```
+
+Using the [vdom Python library](https://github.com/nteract/vdom):
+
+```python
+from vdom import h1, p, img, div, b
+
+div(
+    h1('Our Incredibly Declarative Example'),
+    p('Can you believe we wrote this ', b('in Python'), '?'),
+    img(src="https://media.giphy.com/media/xUPGcguWZHRC2HyBRS/giphy.gif"),
+    p('What will ', b('you'), ' create next?'),
+)
+```
+
+To render a `.vdom` or `.vdom.json` file, simply open it:
+
