First, thank you for considering contributing to ChainLink. We welcome contributions of all sizes!
Please dive in, and feel free to ask questions on our Gitter, open an issue, or send a pull request on GitHub.
Testing is core to our development philosophy. In building an application that will power the infrastructure of the future, we believe that well tested code is of the utmost importance. We do everything we can to ensure that the test suite is stable and maintains a high level of coverage(even if that is difficult with Go). Please write tests for your code and make sure that the existing suite continues to pass. If you run into trouble with this, you can always ask for help in our Gitter.
Please adhere to the [Go Contribution Guidelines]. Specifically, please run go fmt on your code before sending any pull requests.
