+===== What is SLURM? =====
+SLURM is an open-source resource manager designed for Linux clusters of all sizes. It provides three key functions. First it allocates exclusive and/or non-exclusive access to resources (computer nodes) to users for some duration of time so they can perform work. Second, it provides a framework for starting, executing, and monitoring work (typically a parallel job) on a set of allocated nodes. Finally, it arbitrates contention for resources by managing a queue of pending work.

 ===== Starting a Job with sbatch =====
+Setting up all of your options everytime you use srun can be repetitive. Use a batch file and submit that instead!
+Example file 'mybatch':
+  #!/bin/sh
+  #SBATCH -n 4
+  #SBATCH --time=0:60
+  #SBATCH --output=mybatch.out
