Contributions are very welcome. If you want a feature to be added,
chances are it will not happen unless you actually write the code.

To get setup, run `bundle install`.  You
can run the full test suite with `rspec spec/` or `rake`.

All pull requests which add a feature or fix a bug must have the
following things:

* Integration test(s). These generally go into
  `spec/integration/session_spec.rb`, unless it's something specific to
  the driver, in which case it goes in `spec/integration/driver_spec.rb`.
  (So a test for `page.driver.resize` goes in `driver_spec.rb` but a test
  for `page.execute_script` goes in `session_spec.rb`.)
* A [good commit
  message](https://github.com/blog/926-shiny-new-commit-styles)
* An entry into the changelog. This currently resides at the bottom of
  the `README.md` file. Reference the Github issue number if there is an
  associated bug report. Feel free to add your name if you want to be
  credited.

Some other things to bear in mind:

* While PhantomJS is capable of compiling and running CoffeeScript code
  directly, I prefer to compile the code myself and distribute that (it
  makes debugging easier). Running `rake autocompile` will watch the
  `.coffee` files for changes, and compile them into
  `lib/capybara/client/compiled`.
* If you've worked on your changes over time, please squash the commits
  in a sensible manner so that each commit is self-contained. If you
  need to update a pull request with new changes, you can just `git push
  -f` to your branch which will overwrite previous commits that you have
  now squashed.
* Please try to pay attention to and follow the existing coding style.

Thanks! It's really great when people help with Poltergeist's
development.
