 Contact reporting
-~~~~~~~~~~~~~~~~~
+-----------------
 
 Remember that not every combination of two bodies can "report" contacts.
 Static bodies are passive and will not report contacts when hit.
 Kinematic Bodies will report contacts but only against Rigid/Character
 bodies. Area2D will report overlap (not detailed contacts) with bodies
 and with other areas. The following table should make it more visual:
