+# Contributing
+QA-Tools / PHPUnit Extension 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:
+
+## Asking Questions
+Feel free to ask any questions and share your experiences in the [Chat Room](https://gitter.im/qa-tools/qa-tools) and help to improve the documentation.
+
+## Submitting an issues
+- A reproducible example is required for every bug report, otherwise it will most probably be __closed without warning__.
+- If you are going to make a big, substantial change, let's discuss it first.
+
+## Working with Pull Requests
+1. Create your feature addition or a bug fix branch based on __`master`__ branch in your repository's fork.
+2. Make necessary changes, but __don't mix__ code reformatting with code changes on topic.
+3. Check your code using "Coding Standard" (see below).
+4. Commit your code.
+5. Squash your commits by topic to preserve a clean and readable log.
+6. Create Pull Request.
+
+## Checking coding standard violations
+
+This library uses [Coding Standard](https://github.com/aik099/CodingStandard) to ensure consistent formatting across the code base. Make sure you haven't introduced any Coding Standard violations by running following command in the root folder of the library:
+
+```bash
+$> phpcs --standard="vendor/aik099/coding-standard/CodingStandard" src
+```
+
+or by making your IDE ([instructions for PhpStorm](http://www.jetbrains.com/phpstorm/webhelp/using-php-code-sniffer-tool.html)) to check them automatically.
+
+## Contributor Code of Conduct
+
+Please note that this project is released with a [Contributor Code of
+Conduct](http://contributor-covenant.org/). By participating in this project
+you agree to abide by its terms. See [CODE_OF_CONDUCT](CODE_OF_CONDUCT.md) file.
