About the suffix ":shared" of volume option of docker container

Hi, first I'm really appreciate for opening this amazing project as open source.

I'm trying to follow the instruction for building MOONRAY using docker container, but found weird section.

docker run -v /source/openmoonray/building/ubuntu22.04:/building:shared  -v /optix:/optix:shared --network=host --rm -it openmoonray_base

The documentation gets me to add the suffix :shared at the end of the volume directory, but it shows an error that "[My directory] is mounted on /home but it is not a shared mount".

As I know, it is sufficient to use -v /source/openmoonray/building:/building

Is there any special purpose for the :shared keyword?
I couldn't find any matching section from docker document.

Thank you.

There's no special purpose to :shared -- everything should work without this option

commented

Then isn't it better to remove that keyword from the document? it makes the error

I stumbled into this error too when trying #37 (comment), if it's not really needed, I'd vote for removing it too!
