+## Built for real workflows
+
+DeckHTML fits workflows where content already lives in HTML or can be generated
+by code:
+
+- **Agent-generated presentations** — let coding agents author HTML and produce
+  deliverable PPTX or PNG outputs.
+- **Recurring reports** — turn dashboards, metrics, and templated pages into
+  presentation assets from CI or scheduled jobs.
+- **Web-to-deck reuse** — convert hosted pages or ordered HTML files without
+  rebuilding every slide manually.
+- **Local and cloud execution** — run locally with no API key, or use cloud mode
+  for hosted workflows and cloud-only enhancements.
