+
+## How to contribute
+
+- Fix a bug or implement a new thing
+- Include tests for your new feature, preferably a QuickCheck test
+- Make a Pull Request
+
+For new features, please first consider filing a PR to [rust-lang/rust](https://github.com/rust-lang/rust),
+adding your new feature to the `Iterator` trait of the standard library, if you believe it is reasonable.
+If it isn't accepted there, proposing it for inclusion in ``itertools`` is a good idea.
+The reason for doing is this is so that we avoid future breakage as with ``.flatten()``.
+However, if your feature involves heap allocation, such as storing elements in a ``Vec<T>``,
+then it can't be accepted into ``libcore``, and you should propose it for ``itertools`` directly instead.
