 A.I. Duet is composed of two parts, the front-end which is in the `static` folder and the back-end which is in the `server` folder. The front-end client creates short MIDI files using the players's input which is sent to a [Flask](http://flask.pocoo.org/) server. The server takes that MIDI input and "continues" it using [Magenta](https://github.com/tensorflow/magenta) and [TensorFlow](https://www.tensorflow.org/) which is then returned back to the client. 
 
-## INSTALLATION
-
-A.I. Duet only works with [Python 2.7](https://www.python.org/download/releases/2.7/) and it was tested with Node v6. There are two basic ways of installing A.I. Duet: with Docker or without Docker.
-
-If you already have a Python environment setup, install all of the server dependencies and start the server by typing the following in the terminal:
-
-```bash
-cd server
-pip install -r requirements.txt
-```
-
-If this does not work, jump down to the [Docker](#docker) installation instructions, which will walk you through installing A.I. Duet within a Docker container.
-
-If it _did_ install tensorflow and magenta successfully, you can run the server by typing:
-
-```bash
-python server.py
-```
-
-Then to build and install the front-end Javascript code, first make sure you have [Node.js](https://nodejs.org) 6 installed. And then install of the dependencies of the project and build the code by typing the following in the terminal: 
-
-```bash
-cd static
-npm install
-npm run build
-```
-
-You can now play with A.I. Duet at [localhost:8080](http://localhost:8080).
-
 ## DOCKER
 
 [Docker](https://www.docker.com/) is an open-source containerization software which simplifies installation across various OSes. It is the simplest method to build and install both the front-end and back-end components. Once you have Docker installed, you can just run:

 ## MIDI SUPPORT
 
 The A.I. Duet supports MIDI keyboard input using [Web Midi API](https://webaudio.github.io/web-midi-api/) and the [WebMIDI](https://github.com/cotejp/webmidi) library.
