 Use `simulation.launch.py` from `rosbot_gazebo` to start all base functionalities for ROSbot 2, 2 PRO, 2R in the Gazebo simulator.
+If you want to spawn multiple robots use `simulation.launch.py` with the `robots` argument e. g.:
+```bash
+ros2 launch rosbot_gazebo simulation.launch.py robots:='robot1={x: 0.0, y: -1.0}; robot2={x: 1.0, y: -1.0}; robot3={x: 2.0, y: -1.0}; robot4={x: 3.0, y: -1.0}'
+```
+
+If you want to use your own world add to the world's sdf file gazebo sensors plugins inside any `<model>` tag:
+```xml
+<plugin filename="ignition-gazebo-imu-system" name="gz::sim::systems::Imu"/>
+<plugin filename="ignition-gazebo-sensors-system" name="gz::sim::systems::Sensors"/>
+```
+
 > **Warning**
 > The distance sensors' topics types from Gazebo simulation mismatch with the real ones. The range sensors are not implemented yet in the Gazebo Ignition (for more information look [here](https://github.com/gazebosim/gz-sensors/issues/19)). The real type is [sensor_msgs/msg/Range](https://github.com/ros2/common_interfaces/blob/rolling/sensor_msgs/msg/Range.msg) but simulated [sensor_msgs/msg/LaserScan](https://github.com/ros2/common_interfaces/blob/rolling/sensor_msgs/msg/LaserScan.msg). The first value of the `ranges` in [sensor_msgs/msg/LaserScan](https://github.com/ros2/common_interfaces/blob/rolling/sensor_msgs/msg/LaserScan.msg) is the `range` field of [sensor_msgs/msg/Range](https://github.com/ros2/common_interfaces/blob/rolling/sensor_msgs/msg/Range.msg).
