Please see Contributing to ECMAScript for the most up-to-date information on contributing proposals to this standard.

Onboarding Existing Proposals

Proposals that are Stage 1 and above must be transferred to the TC39 GitHub organization for discoverability and archival purposes. To onboard a proposal that lives outside the TC39 organization:

1. Transfer your repository to @bterlson
2. Email @bterlson at brian.terlson AT microsoft.com notifying me of the transfer (github's transfer notification is not the most obvious thing and there's only a short window to accept the transfer)
3. @bterlson will transfer your repository to the TC39 organization.

Note that as part of the onboarding process your repository name may be normalized. Don't worry, redirects will continue to work.
