            <p>The authors of a ZIP are responsible for building consensus within the community and documenting / addressing dissenting opinions.</p>
            <p>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 <a href="https://discord.gg/kdjfvps">ZcashCommunity Discord chat</a> to talk about your idea.</p>
            <p>Participation in the Zcash project is subject to a <a href="https://github.com/zcash/zcash/blob/master/code_of_conduct.md">Code of Conduct</a>.</p>
            <p>The Zcash protocol is documented in its <a href="protocol/protocol.pdf">Protocol Specification</a>.</p>
            <p>To start contributing, first read <a href="zip-0000">ZIP 0</a> which documents the ZIP process. Then clone <a href="https://github.com/zcash/zips">this repo</a> from GitHub, and start adding your draft ZIP, formatted either as reStructuredText or as Markdown.</p>
            <p>For example, if using reStructuredText, use a filename matching <code>draft-*.rst</code>. Use <code>make</code> to check that you are using correct <a href="https://docutils.sourceforge.io/rst.html">reStructuredText</a> or <a href="https://pandoc.org/MANUAL.html#pandocs-markdown">Markdown</a> syntax, and double-check the generated <code>draft-*.html</code> file before filing a Pull Request.</p>
