# resp-modifier [](https://travis-ci.org/shakyShane/resp-modifier)
|
||||
|
||||
All the good parts from [connect-livereload](https://github.com/intesso/connect-livereload) without
|
||||
the livereload specific bits & with multiple replacements added.
|
||||
|
||||
## Contributing
|
||||
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using [Gulp](http://gulpjs.com/).
