+# 3D Physics Tests
+
+This demo contains a series of tests for the 3D 
+physics engine.
+
+They can be used for different purpose:
+- Functional tests to check for regressions and 
+compare the behavior between physics engines
+- Performance tests to evaluate and compare 
+performance between physics engines
+
+Language: GDScript
+
+Renderer: GLES 2
