+## Contributing
+
+We at API By Example, encourage anyone to contribute to any of our repositories.
+
+### Code Styles
+
+Please see https://github.com/rockabox/rb-js-linter for JS Style information.
+
+### Pull requests
+
+If you fixed or added something useful to the project, you can send a pull request.
+It will be reviewed by maintainer and accepted, or commented for rework, or declined.
+
+### Bugs
+
+If you found an error, typo or any other flaw in the project, please report about
+it using GitHub Issues. The more details you provide, the easier it could be
+reproduced and the faster it could be fixed. Unfortunately, sometimes the bug
+can only be reproduced in your project or in your environment, so maintainers
+cannot reproduce it. In this case we believe you can fix the bug and send us the
+fix.
+
+### Features
+
+If you've got an idea about a new feature, it's most likely that you'll have to
+implement it on your own. If you cannot implement the feature, but it is very
+important, you can create an issue at GitHub, but expect it to be declined by
+the maintainer.
