bips/README.mediawiki

People wishing to submit a BIP should first describe their idea to the [https://groups.google.com/g/bitcoindev bitcoindev@googlegroups.com]
mailing list to gather feedback on viability and community interest before working on a
formal description. Please open a pull request to this repository only when substantial progress on the draft has been
made, preferably when the draft is nearing completion. Authors do <em>not</em> assign a number to their own proposal.
After a proposal meets the editorial criteria, a BIP Editor will assign a number to it and publish the proposal by
merging the pull request to the repository. Please see [[bip-0003.md|BIP 3: Updated BIP Process]] for the full process.

The BIPs repository serves as a publication medium and archive. Having a BIP published here indicates that the proposal
is in scope and has met other formal criteria for this repository, but does not indicate that it is a good idea, has
community consensus, or that it is about to be adopted. The BIP Editors are expected to be liberal with publishing BIPs
and to try not to be too involved in decision-making on behalf of the community. Beyond the formal criteria, evaluation of
the proposals is left to the audience of the repository. When a proposal is controversial and it cannot be agreed upon
whether it should be published, the conservative option will always be preferred: the proposal will be closed.

Those proposing and opposing changes should consider that ultimately acceptance and adoption rests with the Bitcoin
users (see also: [https://en.bitcoin.it/wiki/Economic_majority economic majority]).
