-The instructions below assume you have cloned this repository and are in the repository directory. For example:
+Begin by cloning the StormSpeed repository and checking out the CAM code and externals
 ```
+cd /scratch/cluster/$USER
 git clone https://github.com/NCAR/StormSPEED
 cd StormSPEED
 git checkout stormspeed
 ./manage_externals/checkout_externals
 ```
