Shouldn't we recommend building images in Docker, not Singularity?

[paulstey]

In the Building Images section we point users to some Singularity docs on how to build images.

I think we might want to point to some Docker examples instead. I've always thought it was much simpler to create a Docker container and then have Singularity do the conversion when we go to actually use it.

If keeping the singularity docs rather than replacing with Docker examples, the Singularity docs for the "building a container" link appears to be outdated. It points to the new documentation page on apptainer.org.
