Recipes are the "give me code I can paste" shape. Each one is small, self-contained, and runnable. They're organized below by the [workflow stage](/1.-introduction/the-stratix-workflow.md) they map to — **Select**, **Build**, **Observe**, **Evaluate**, **Improve** — plus cross-cutting groupings (industry, integration, migration, SDK basics) at the bottom. If you're new, start with [Top 5 starter recipes](https://github.com/LayerLens/gitbook-full/blob/main/02-get-started/top-5-starter-recipes.md).
