I think this is a documentation issue. I get this same error if I try running a teletype command outside of the app directory:

[katelyn@h code]$ teletype new my-cool-app

The "Overview" section of the README makes it seem like you'd run these commands in succession; but in reality, you need to cd into 'my-cool-app' first.

In addition to a doc update, it may be nice to check if the PWD is a valid teletype app.
