+
+## Enable debug rendering
+
+Setting DALI_DEBUG_RENDERING environment variable will enable the renderer debuging.
+
+Then, every concrete control renderer( ColorRenderer, BorderRenderer, ImageRenderer, GradientRenderer, etc. ) is replaced with a DebugRenderer object.
+Debug renderer renders a simple quad wireframe, so that the control layout and scene structure is clearly displayed.
+
+### Example:
+~~~{.bash}
+sh-4.1$ DALI_DEBUG_RENDERING=1 /usr/apps/com.samsung.dali-demo/bin/blocks.example
+~~~
