• 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, 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.
