-## Running ORCA 5.0.0 and Higher in Parallel
+## Example Submission Script
 
-On Barbora cluster and Karolina cluster, version 5.0.1 is available. However, to run it in parallel you need to specify execution nodes via `inputfilename.nodes` file. Additionally, all calculations **must** be run on SCRATCH.
+The following script contains all of the necessary instructions to run an ORCA job, including copying of the files to and from /scratch to utilize the InfiniBand network:
