+## Scene provider
+
+This example demonstrates how to populate and update a 3D scene using
+Ignition Transport.
+
+This example is meant to be used with `examples/config/scened.config`, which
+loads the `Scene3D` plugin to create the scene, and the `TransportSceneManager`
+plugin to update the scene using Ignition Transport.
+
+## Build
+
+```
+cd examples/standalone/scene_provider
+mkdir build
+cd build
+cmake ..
+make
+```
+
+## Run
+
+In one terminal, start the scene provider:
+
+```
+cd examples/standalone/scene_provider/build
+./scene_provider
+```
+
+On another terminal, start the example config:
+
+```
+
+```
