Singularity is installed on `eic0.phy.anl.gov`, `bebop.lcrc.anl.gov`, and most HPC systems.
Singularity ships the entire container image in a single file.  See the extensive singularity documentation to learn more. 
```bash
git clone git@eicweb.phy.anl.gov/containers/eic_container.git
cd container 
```
