 Prebuilt container images provide a convenient starting point, but they may not contain all of the software required for a particular project.
 
 Most Apptainer images are distributed as `.sif` files, which are typically read-only. If you need to install additional software or make persistent changes to a container, Apptainer provides overlays, which add a writable layer on top of the original image while leaving the `.sif` file unchanged.
