 To try it yourself, there is a `long.npy` file, rename it to `load.npy` (backup `load.npy` before doing so) and run `demo.py`,
 you will see the bird failing more often than not. `long.py` was trained for only 100 more epochs than `load.npy`.

+Web Server
+----------
+
+To setup the web server, after installing the dependencies by running `pip install -r requirements`, follow the steps below:
+
+```
+cd web
+npm install
+node server.js
+```
+
+You may want to use [pm2](https://github.com/Unitech/pm2) to run the server as a daemon in the background.
+
+Now you can redirect traffic to the port the server is listening on (8088 by default).

+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this

+      of your accepting any such warranty or additional liability.

+Floppy Bird
+=========
+Initially, I wanted to try recreating Flappy Bird in HTML5, using a canvas and recycling the assets from the old game.
+
+What I did instead is something way more primitive. This project uses nothing but good ol' div's for all the objects and graphics, will scale perfectly on almost any screen (mobile and desktop), is terribly unoptimized, laggy, and isn't nearly as fast as it would've been if I had just used a canvas instead. But here it is!

+Notice
+=====
+The assets powering the visual element of the game have all been extracted directly from the Flappy Bird android game. I have only done the coding, not designed the visual elements.  
+I do not own the assets, nor do I have explicit permission to use them from their creator. They are the work and copyright of original creator Dong Nguyen and .GEARS games (http://www.dotgears.com/).  
+I took this Tweet (https://twitter.com/dongatory/status/431060041009856512 / http://i.imgur.com/AcyWyqf.png) by Dong Nguyen, the creator of the game, as an open invitation to reuse the game concept and assets in an open source project. There is no ill intention to steal the game, or claim it as my own. This is merely a recreation for fun.  
+If the copyright holder would like for the assets to be removed, let me know!
