# Applications Worked examples: three services built on the framework, each written up as what it is and what it asked of the framework. The calendar is the framework's own example and needed no change; the forum is a real in-tree service; and the weather, the first deployed service, now lives in its own repository. Together they keep the framework honest — nothing in `packages/sextile/` knows a forum, a calendar or the weather. ```{toctree} :maxdepth: 1 calendar stardot weather ```
