.. Title: Specifications and Zcash Improvement Proposals What are ZIPs? -------------- Zcash Improvement Proposals (ZIPs) are the way to: * propose new features for the the `Zcash cryptocurrency `__ and their rationale, * specify the implementation details of the feature, * collect community input on the proposal, and * document design decisions. Contributing ------------ The authors of a ZIP are responsible for building consensus within the community and documenting / addressing dissenting opinions. Anyone can write a ZIP! We encourage community contributions and decentralization of work on the Zcash protocol. If you’d like to bounce ideas off people before formally writing a ZIP, we encourage it! Visit the `ZcashCommunity Discord chat `__ to talk about your idea. Participation in the Zcash project is subject to a `Code of Conduct `__. The Zcash protocol is documented in its `Protocol Specification `__. To start contributing, first read `ZIP 0 `__ which documents the ZIP process. Then clone `this repo `__ from GitHub, and start adding your draft ZIP, formatted either as reStructuredText or as Markdown. For example, if using reStructuredText, use a filename matching ``draft-*.rst``. Use ``make`` to check that you are using correct `reStructuredText `__ or `Markdown `__ syntax, and double-check the generated ``draft-*.html`` file before filing a Pull Request.
