+## Quickstart
+
+This is a quickstart guide of how you can typically use this *LabInstance to deploy MPI programs*
+
+- Working Directory
+
+> /project
+
+- Default user for MPI
+
+> mpi
+
+- The host file that contains addresses of connected workers can created with:
+
+> IP_ADDR=$(ip addr show | grep "inet " | grep  "eth0" | awk '{print $2}')
+> nmap -sP $IP_ADDR  | grep ondemand_mpi_worker | awk  -F "[()]" '{ for (i=2; i<NF; i+=2) print $i }' > /project/hosts
+
+- Compile
+
+> mpicc -o /project/mpi_hello_world examples/mpi_hello_world.c
+
+- run the MPI hello world program
+
+sudo -u mpi mpirun -n 10 -f /project/hosts  /project/mpi_hello_world
