+### Batch system
+
+For the **frequency_narrow_sweeps_long** program, the is a script called 
+**job.script** that comes along with it. This is to be able to run it on a
+batch system using Slurm if you have access to one. 
+This is the recommended way to use this program as it takes approximately 90 
+minutes to complete when using 16 cores.
+
+If you happen to have such a system available to you, then you should clone
+this repo on that system, then compile it by running:
+
+```shell
+    make frequency_narrow_sweeps_long
+```
+
+You might have to load the Armadillo library before compiling.
+
+After compiling, you can schedule it by running:
+
+```shell
+    sbatch job.script
+```

 ## Performance
 
 This section aims to give an idea to the time it takes for the program to
