This documentation needs work. See "Help improve this page" in the sidebar.

Drupal version: ^9.5, ^10, or ^11
Required modules (installed as dependencies automatically):
- entity_share (base module, ^3.0@RC)
- views_custom_cache_tag (^1.3)
PHP extension: cURL (recommended for the hub — without it, SSRF protection has a DNS-rebinding window and dual-resolution hostnames are refused outright; a warning appears on /admin/reports/status)
Two Drupal sites (or two site configurations): one acting as the Hub/server, one as the Subscriber/client
Cron: Both sites need working cron — the hub uses a queue (entity_share_websub) to process outbound notifications, and the subscriber uses queues for async entity import
