+README for start-coaster-workers.sh
+===================================
+
+start-coaster-workers.sh is a custom script to get coaster-service and workers
+started.
+
+To begin, you must have access to Tukey and Vesta systems in the ALCF. These
+systems require a cryptocard to authenticate an ssh session. Next, run:
+-----
+$ ./start-coaster-workers.sh
+-----
+When prompted for the password, enter the password for vesta.
+Once the script completes, a  sites.xml file would be generated that could be
+used by swift to connect to the active coaster-service and submit jobs to the
+worker on Vesta.
