 # Runner Size Converter Action
 
 A composite action that converts a runner size into an arm64 GitHub runner name.
-By default it resolves the Blacksmith arm64 cloud runners; set
-`use-blacksmith-runners: false` to resolve the self-hosted `linux-arm64` runners
-instead, or `use-arc-runners: true` to resolve the self-hosted ARC runners
-(this takes precedence).
+With `use-arc-runners: true` it resolves the self-hosted ARC runners; otherwise
+it resolves the GitHub-hosted `linux-arm64` larger runners.

 In a public repository (`github.event.repository.private == false`) the output is always `ubuntu-24.04-arm`, GitHub's standard arm64 runner, whatever the inputs. ARC is only used in private repositories; when the event has no repository (e.g. `schedule`), the table above applies without ARC.
