 # Contributing
 
-Contributions are welcome and will be fully credited.
+Contributions are welcome, and are accepted via pull requests. Please review these guidelines before submitting any pull requests.
 
-We accept contributions via Pull Requests on [GitHub](https://github.com/staudenmeir/dusk-updater).
+## Guidelines
 
-## Pull Requests
+* Please follow the [PSR-2 Coding Standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md).
+* Ensure that the current tests pass, and if you've added something new, add the tests where relevant.
+* Remember that we follow [SemVer](http://semver.org). If you are changing the behaviour, or the public api, you may need to update the docs.
+* Send a coherent commit history, making sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please [squash](http://git-scm.com/book/en/Git-Tools-Rewriting-History) them before submitting.
+* You may also need to [rebase](http://git-scm.com/book/en/Git-Branching-Rebasing) to avoid merge conflicts.
 
-- **[PSR-2 Coding Standard](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md)** - The easiest way to apply the conventions is to install [PHP CS Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer).
+## Running Tests
 
-- **Add tests** - Your patch won't be accepted if it doesn't have tests.
+You will need an install of [Composer](https://getcomposer.org) before continuing.
 
-- **Document any change in behaviour** - Make sure the `README.md` and any other relevant documentation are kept up-to-date.
+First, install the dependencies:
 
-- **Consider our release cycle** - We try to follow [SemVer v2.0.0](http://semver.org). Randomly breaking public APIs is not an option.
+```bash
+$ composer install
+```
 
-- **Create feature branches** - Don't ask us to pull from your master branch.
+Then run phpunit:
 
-- **One pull request per feature** - If you want to do more than one thing, send multiple pull requests.
+```bash
+$ vendor/bin/phpunit
+```
 
-- **Send coherent history** - Make sure each individual commit in your pull request is meaningful. If you had to make multiple intermediate commits while developing, please [squash them](http://www.git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Changing-Multiple-Commit-Messages) before submitting.
+If the test suite passes on your local machine you should be good to go.
 
-## Running Tests
-
-```
-vendor/bin/phpunit
-```
+When you make a pull request, the tests will automatically be run again by [Travis CI](https://travis-ci.org/) on multiple php versions and hhvm.
