 If you don't see a pending PR, there are no changes to publish from `main`.
 
+### npm authentication
+
+The `publish.yml` workflow uses npm trusted publishing (OIDC) for publishing
+`prismic` and removing closed PR tags. Enable **Allow npm dist-tag** for the
+`prismicio/cli` trusted publisher in the package's npm settings. Tag operations
+require npm 11.21.0 or later; the prerelease job installs that version explicitly.
+
+The workflow does not use `NPM_TOKEN`. Publishing updates the `canary` or `pr-N`
+tag, and closing a PR removes its tag. Superseded versions remain installable and
+are no longer automatically deprecated because `npm deprecate` does not support
+OIDC.
