 **Note**: You could use [slam_toolbox](https://github.com/SteveMacenski/slam_toolbox) instead but you need to use this [experimental branch](https://github.com/robo-friends/m-explore-ros2/tree/feature/slam_toolbox_compat) which is still under development.
 
-#### Nav2 gazebo spawner
+#### Nav2 gazebo spawner (deprecated in humble)
 To spawn multiple robots, you need the `nav2_gazebo_spawner` which does not come up with the `nav2-bringup` installation. For that, install it with `sudo apt install ros-${ROS_DISTRO}-nav2-gazebo-spawner`.
+Note that was the case for release previous to `humble` but since `humble` release, this package is deprecated and a gazebo node is used for this. So, if you are using `humble` or newer, you don't need to install it.
+
 #### Nav2 config files
-This repo has some config examples and launch files for running this package with 2 TB3 robots and a world with nav2. Nonetheless, they are only compatible with the galactic branch and since some breaking changes were introduced in this branch, if you want to try it with another ros2 distro you'll need to tweak those param files for that nav2's distro version (which shouldn't be hard).

 ### Running the demo with TB3
 First, you'll need to launch the whole simulation stack, nav2 stacks and slam stacks per robot. For that just launch::
