Prophet has a non-fixed release cycle but we will be making bugfixes in response to user feedback and adding features. Its current state is Beta (v0.3), we expect no obvious bugs. Please let us know if you encounter a bug by [filing an issue](https://github.com/facebook/prophet/issues). Github issues is also the right place to ask questions about using Prophet.
If you plan to contribute new features or extensions to the core, please first open an issue and discuss the feature with us. Sending a pull request is fine too, but it will likely be merged more quickly if any design decisions are settled on beforehand in an issue.
Most of the `doc` pages are generated from [Jupyter notebooks](http://jupyter.org/) in the [notebooks](https://github.com/facebook/prophet/tree/master/notebooks) directory at the base of the source tree. Please make changes there and then rebuild the docs:
