 Using Singularity
-*****************
+=================
 
 `Singularity <https://sylabs.io/>`__ is another container platform able to run Docker images. 
 Singularity can be run both on local machins and in instances where the user does not have root access. 
 Instances where a user may not have root privlidges include HPC clusters and cloud cluster resources.
 A container is a single file without anything else to install.

 ClusterODM, NodeODM, SLURM, with Singularity on HPC
-***************************************************
+===================================================
 
 
 You can write a SLURM script to schedule and set up available nodes with NodeODM for the ClusterODM to be wired to if you are on the HPC. Using SLURM will decrease the amount of time and processes needed to set up nodes for ClusterODM each time. This provides an easier way for user to use ODM on the HPC.
