1. Clone project
2. Copy config.json.sample to config.json
3. Edit config.json for your setup
4. [Install Node.js](https://github.com/nodesource/distributions/blob/master/README.md#installation-instructions)
4. `npm install` (node.js dependencies)
5. `make all` (Python dependencies, mpg321 dependency)
5. `virtualenv lib` # make a python virtualenv
6. `lib/bin/pip install -r requirements.txt`
TODO: Can this be streamlined? Maybe move Makefile commands into `npm` commands.
