 ## Errors building SOCTools
 If there are any errors during building of SOCTools then it is often best to start from the top. The easiest way is to delete any existing Docker images that are already built and then restart the installation. To prune existing Docker images run `docker system prune -a`. This command will delete all images so it assumes that SOCTools is the only service running on the server.
