Contributing------------Prophecy is an open source, community-driven project. If you'd like to contribute,feel free to do this, but remember to follow these few simple rules:- Make your feature addition or bug fix,- Add either specs or examples for any changes you're making (bugfixes or additions) (please look into `spec/` folder for some examples). This is important so we don't break it in a future version unintentionally,- Commit your code, but do not mess with `CHANGES.md`,Running tests-------------Make sure that you don't break anything with your changes by running:```bash$> composer install--prefer-dist$> vendor/bin/phpspec run```
