This plugin implements the NodeInfo standard for content management systems, allowing a site to share public metadata with other servers in the Fediverse. It is essential for developers and site administrators who want their platform to be discoverable and interoperable within decentralized social networks like Mastodon.

NodeInfo Endpoints: Creates standardized JSON endpoints (/.well-known/nodeinfo and REST API paths) that automatically publish information about your site's software, usage statistics, and supported federation protocols.

Extensible Data: The exposed metadata is filter-based, allowing other plugins to add their own protocols (like ActivityPub) or services, ensuring the information stays current as your site's capabilities expand.

Version Support: Provides compatibility with all major NodeInfo specification versions (1.0, 1.1, 2.0, 2.1, 2.2) and the NodeInfo2 format, ensuring broad interoperability with different fediverse software.

Site Health Integration: Includes built-in checks in the admin panel to verify that all required endpoints are correctly configured and publicly accessible, simplifying troubleshooting.

Public Data Only: Shares only non-sensitive, aggregate information such as site name, description, post counts, and user numbers, maintaining privacy while enabling federation.
