.. 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 <https://z.cash/>`__ 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 community
`Discord <https://discord.com/invite/PXHqXV2>`__ channel to talk about your idea.
Participation in the Zcash project is subject to a `Code of
Conduct <https://github.com/zcash/zcash/blob/master/code_of_conduct.md>`__.
The Zcash protocol is documented in its `Protocol Specification <protocol/protocol.pdf>`__.
To start contributing, first read `ZIP 0 <zip-0000.rst>`__ which documents the ZIP process.
Then clone `this repo <https://github.com/zcash/zips>`__ 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 <https://docutils.sourceforge.io/rst.html>`__ or
`Markdown <https://pandoc.org/MANUAL.html#pandocs-markdown>`__ syntax,
and double-check the generated ``draft-*.html`` file before filing a Pull Request.
