[Other issue]: Can not find information about suitable rmf demos version for distribution

Description

Hello RMF team, I would like to install your framework but I can't find the information about which rmf_demos version to use for different ROS2 distros (I use kilted). I would like to follow this instruction from your installation guide:

Next create a ROS 2 workspace and build rmf_demos from source. Replace the 2.0.3 tag below with the version of rmf_demos for your distribution.

mkdir ~/rmf_ws/src -p
cd ~/rmf_ws/src
git clone https://github.com/open-rmf/rmf_demos.git -b 2.0.3
cd ~/rmf_ws
colcon build

If I try to just run it with -b 2.0.3, I get the following error:

`mkdir ~/rmf_ws/src -p
cd ~/rmf_ws/src
git clone https://github.com/open-rmf/rmf_demos.git -b 2.0.3
cd ~/rmf_ws
colcon build

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

git switch -c

Or undo this operation with:

git switch -

Turn off this advice by setting config variable advice.detachedHead to false

Is there an overview somewhere that shows which rmd_demos version is compatible with which ROS2 distro?

There are two different issues there:

• The tag you are using is too old, 2.0.3 was released in June 2023 so it probably targets Iron. Use the latest tag or just the kilted branch.
• The error you are seeing suggests to me you didn't source your ROS 2 installation source /opt/ros/kilted/setup.bash.
