+title: Keeping registry and list information current
+linkTitle: Updating
+---
+
+We periodically review [registry](..) entry and [list data], such as external
+links, to ensure that only [adopters](../../adopters/),
+[distributions](../../distributions/),
+[integrations, libraries](../../integrations/), and [vendors](../../vendors/)
+actively supporting OpenTelemetry are included in the registry.
+
+Entry authors are encouraged to maintain links to active and up-to-date
+distributions, documentation, and libraries. We reserve the right to update or
+remove entries for components that seem to no longer actively support
+OpenTelemetry. This may happen, for example, when external links become invalid.
+We will attempt to contact the GitHub user who submitted the original entry data
+on a best effort basis, but otherwise reserve the right to edit and remove
+entries and entry data.
