+- `artifact-url`: Ecosystem release URL, such as a PyPI version page. Omit it for a GitHub-only project. A project that
+  publishes several packages puts one URL per line; the links share one line of the body, separated by commas.
+- `artifact-label`: Link text for each `artifact-url` line, in the same order; default `PyPI release`. Use `Zipapp` or
+  another product name for a different artifact. `release-creator` adds an emoji for the link's ecosystem.
 
 The Action reads `GITHUB_REPOSITORY` for PR and comparison links. A repository with separate release namespaces, such as
 toml-fmt, calls `release-creator notes --package` directly for its package changelog.

+`render-release-notes` takes one `artifact-url` per line, with matching `artifact-label` lines, so a project that
+publishes several packages lists them all on one row of the GitHub Release. Release bodies now come from
+`release-creator` 4.3.0, which marks each link with its ecosystem emoji.
