  • we adopted Contributor Covenant. Oustanding items:
    • need a openjsf affiliated email address for reporting

Review the remaining checklist items, especially the Project Charter linked to loopback-governance#22 and the legal copyright notice, alongside the existing pages/en/contrib/Governance.md and the linked charter template. Confirm which items are still outstanding and update the checklist when the charter, copyright notice, and other onboarding requirements are complete.
