+## Content
+
+The following examples are part of this demo repository:
+
+* Example 1: [*RRBot*](example_1)
+
+   *RRBot* - or ''Revolute-Revolute Manipulator Robot'' - a simple position controlled robot with one hardware interface. This example also demonstrates the switching between different controllers.
+
+
+* Example 2: [*DiffBot*](example_2)
+
+   *DiffBot*, or ''Differential Mobile Robot'', is a simple mobile base with differential drive.
+   The robot is basically a box moving according to differential drive kinematics.
+
+
+* Example 3: ["RRBot with multiple interfaces"](example_3)
+
+   *RRBot* with multiple interfaces.
+
+
+* Example 4: ["Industrial robot with integrated sensor"](example_4)
+
+   *RRBot* with an integrated sensor.
+
+
+* Example 5: ["Industrial Robots with externally connected sensor"](example_5)
+
+   *RRBot* with an externally connected sensor.
+
+* Example 6: ["Modular Robots with separate communication to each actuator"](example_6)
+
+   The example shows how to implement robot hardware with separate communication to each actuator.
+
+* Example 7: "Multi-robot example (tba.)"
+
+* Example 8: ["Using transmissions"](example_8)
+
+   *RRBot* with an exposed transmission interface.
+
+* Example 9: "Gazebo Classic and Gazebo Sim (tba.)"
