-After installing the middleware, during spec load, plugin will try to find `<specPath>/index.jsx` or `<specPath>/src/index.jsx` file, analyze it and expose raw and rendered data objects. Data will be then available within [EJS Spec pre-rendering](http://sourcejs.com/docs/spec-helpers/#native-templating) (enabled by default).
