+## File Modification Dates
+
+GitHub Pages deployments will set the modification date of uploaded files to the time of deployment, not the original file's last modified date. This is a limitation of the platform and cannot be changed by this action.
+
+**Note:** If you provide `artifact_id`, it will be used directly for deployment and as the build version for uniqueness. This is useful if you have multiple artifacts with the same name in your workflow run.
