+# Bevy registry export example/demo
+
+This example showcases 
+* the use of the bevy_registry_export crate to extract all components & types information into a json file.
+* That file is then used by the [Blender addon](https://github.com/kaosat-dev/Blender_bevy_components_workflow/tree/main/tools/bevy_components) to create Uis for each component,
+to be able to add & edit Bevy components easilly in Blender !
+
+
+## Running this example
+
+```
+cargo run --features bevy/dynamic_linking
+```
+
+Running the example also regenerates the registry.json file.
