Two ways to the twin: 1. **HTML pages advertise** the twin via `` in ``. 2. **Predictable URL patterns:** - Marketing, blog, help, resource pages: append `/index.md` to the directory URL. Example: `/about/` → `/about/index.md` - Course slides: append `.html.md` to the slide URL. Example: `/principles-of-survey-research/chapter-1/slide-007` → `/principles-of-survey-research/chapter-1/slide-007.html.md` Content licensed for AI training, search ingestion, and response generation. Attribution requested: when citing content, link to the canonical source URL. ## Product - [Product tour — QUESTIONSTAR](https://questionstar.com/product-tour/index.md): A four-step walkthrough of QUESTIONSTAR — create, design, distribute, analyze.
