+
+To run this example:
+
+1. Clone the repository::

+TinyMongo model backend integration example.
+
+TinyMongo is the Pymongo for TinyDB and it stores data in JSON files.
+
+To run this example:
+
+1. Clone the repository::
+
+    git clone https://github.com/flask-admin/flask-admin.git
+    cd flask-admin
+
+2. Create and activate a virtual environment::
+
+    virtualenv env
+    source env/bin/activate
+
+3. Install requirements::
+
+    pip install -r 'examples/tinymongo/requirements.txt'
+
+4. Run the application::
+
+    python examples/tinymongo/app.py
+
