Also use when the user mentions "HowTo section," "how-to section," "steps section," "quick start," "walkthrough," "tutorial block," "3 steps," "N steps," "simple steps," "tutorial steps," "step-by-step block," "HowTo schema," "HowTo JSON-LD," "instruction steps," "numbered steps SEO," "horizontal tabs for steps," or "procedure section." This skill is for a section inside a page, not a full page template—use article-page-generator, docs-page-generator, or tools-page-generator for page-level layout. For FAQ Q&A blocks, use faq-page-generator. For structured data details beyond HowTo, use schema-markup. For article body copy only, use article-content.
