horizon-elm-chat-app's Issues

Having issues getting this up and running

Hi. I am really excited about Elm and Horizon and wanted to try this out. I am having some issues and was curious if you could add a few extra details on the steps to get this started.

The steps that I followed were:

1. git clone the repo
2. npm install
3. hz init elm_chat

The app itself runs. I get to Horizon ready for connections in terminal. But I get the error: "unexpected token e in JSON at position 0" and Chrome shows a blank screen in the browser.

I think for total beginners, adding something about needing to run hz init to get a .hz file would be helpful and I am curious if you have seen this error before.

Elm: 0.17, Rethink 3.2.1, Node 4.4.

Thank you again for doing this!

npm start fails

The most likely cause is: this directory doesn't contain an .hz directory
