+ReactFire Todo App Example
+==========================
+
+Live Demo
+---------
+You can view a live version of this demo [here](https://reactfiretodoapp.firebaseapp.com/).
+
+Setup Instructions
+--------------------
+To run this example locally, either download the whole ReactFire repo or just this /todoApp/
+directory. From the /todoApp/ directory, install the needed dependencies via bower:
+
+```bash
+$ bower install
+```
+
+Then start up a server via Python (or your favorite method):
+
+```bash
+$ python -m SimpleHTTPServer 8080
+```
+
+Now you should be able to visit the example in the browser of your choice at [http://127.0.0.1:8080/](http://127.0.0.1:8080/).
+
+Description
+-----------
+This example shows three different ways to make a Todo app using React. It is adapted from the
+Todo app example on the [ReactJS homepage](http://facebook.github.io/react/). There are three
+different versions of the Todo app example:
+
+1. __Plain React:__ Almost an exact copy of the ReactJS homepage example. This uses plain React
+code with no Firebase code at all. Changes made to this example are not persistent.
+
+2. __React + Plain Firebase:__ A version of the first example with explicit Firebase calls. Changes
+made to this example are persistent.
+
+3. __ReactFireMixin:__ A version of the first example which uses the ReactFireMixin. Changes made to
+this example are persistent.
+
+Walkthrough
+-----------
+To learn more about how this example works, see the [blog post on the official Firebase blog](https://www.firebase.com/blog/2014-05-01-using-firebase-with-react.html).
