+# Yawn addon cookbook
+
+These recipes deliberately avoid another application framework or renderer wrapper.
+Import the function you need and pass the same `YawnCore` instance to every addon.
+
+| Recipe | Demonstrates |
+| --- | --- |
+| `01-canonical-ast.js` | A shared DAG output and canonical S-expression serialization |
+| `02-jso-graph.js` | Plain JavaScript object authoring |
+| `03-fluent-builder.js` | Fluent render-graph authoring |
+| `04-fxnode-export.js` | Exporting an FXNode snapshot to the canonical AST |
+| `05-default-pipelines.js` | Attaching optional external WGSL declarations |
+| `06-custom-render-pipeline.js` | Supplying a custom scene render shader |
+| `07-compute-pipeline.js` | Supplying a binding-free compute pass |
+| `08-compile-and-switch.js` | Compiling, activating, and safely cleaning up a graph |
+| `09-gltf-import-worker.js` | Fetching a glTF URL into shared memory from a worker |
+| `10-mesh-instances.js` | Creating and mutating conventional instance handles |
+| `11-custom-soa-column.js` | Allocating an instance-sized shared SOA column |
+| `12-direct-sab-animation.js` | Updating transforms through generation-guarded SAB writes |
+| `13-bvh-picking.js` | Ray picking through the mesh-handles addon |
+| `14-worker-to-worker.js` | Using core from another worker through a `MessagePort` |
+| `15-complete-scene.js` | Combining the graph, glTF, and mesh addons |
+
+Recipes 1–7 isolate graph authoring concepts, so their ASTs are intentionally
+fragments rather than complete renderable loadouts. Recipe 15 uses the complete
+scene graph from `render-graph-studio` when an end-to-end example is needed.
