 ### Execution
 Once you've downloaded the script and prepared the configuration file, run this script `script wordpress.log ./wordpress-jail.sh`.  The script will run for several minutes.  When it finishes, your jail will be created, and WordPress will be installed with all its dependencies. Next, complete the post-installation tasks.
