On my computer, the example can only be run if I modify this

   let font_handle = asset_server.load("../assets/FiraSans-Bold.ttf").unwrap();

Hi! The examples are supposed to be run from the root directory of the repository. This is why the font is expected to be found on the assets/ instead of ../assets. Maybe we should just try both paths in case someone runs the examples from the bevy_rapier2d or bevy_rapier3d folders as you appear to have done.

I think it would be better to add a readme file

We're no longer using fonts so this issue can be closed.
