+# Contribution Guidelines
+We welcome you to report [issues](/../../issues) or submit [pull requests](/../../pulls).  While the below guidelines are necessary to get code merged, you can
+submit pull requests that do not adhere to them and we will try to take care of them in our spare time.  We are a smallish group of developers,
+though, so if you can make sure the build is passing 100%, that would be very useful.
+
+We recommend including details of your particular usecase(s) with any issues or pull requests.  We love to hear how our libraries are being used
+and we can get things merged in quicker when we understand its expected usage.
+
+## Pull Requests
+Code changes should be sent through [GitHub Pull Requests](/../../pulls).  Before submitting the pull request, make sure that phpunit reports success
+by running:
+```sh
+./vendor/bin/phpunit
+```
+And there are not coding standard violations by running
+```sh
+./vendor/bin/phpcs
+```
+
+## Builds
+While the build does not strictly enforce 100% code coverage, it will not allow coverage to drop below its current percentage.
+[Scrutinizer](https://scrutinizer-ci.com/) is used to ensure code quality and enforce the [coding standard](http://www.php-fig.org/psr/psr-2/).
