Document build process

[aral]

To reproduce

1. Fork express-ws

2. Include your fork via its GitHub URL in your project (e.g., github:aral/express-ws#referential-routes – this will actually demonstrate the problem)

3. Run your app/tests.

What should happen

It should work.

What actually happens

…/node_modules/express-ws/index.js:1
Error: Cannot find module './src/index'`

Why it happens

There is an .npmignore file that ignored the src/ directory.

The actual issue

There’s a pre-publish process that uses Babel that’s not documented or captured in the repository.

Suggested fix

Document build process and add any necessary configuration / dev-dependencies to the repository.

Workaround

Delete the .npmignore file.
