+Contributor Guidelines
+======================
+
+Hi! Thank you for your interest in contributing to this open source library!
+We ask that you follow the following style guidelines when submitting pull
+requests, to keep the code consistent and maintainable.
+
+ - Do not put an if clause and it's statement on the same line: separate them
+   with a new-line and indent accordingly.
+
+(This file will be expanded as more guidelines are established by the maintainer)
