The terminal on your right should be starting a MySQL Docker Container to connect our wordpress to. This is a fairly routine step.
When MySQL is ready, run either of the commands below to start wordpress in Plain Mode/Stock Mode (WordPress as it exists everywhere on the planet), or start it in Polyscripted Mode (A WordPress that is unique to this specific instance on your right.)
docker run --name wp-cont --link mysql-cont:mysql -p 80:80 -d polyverse/demo-wp-standard
NOTE: This version takes JUST a bit longer to start because it's generating a new PHP on the fly, as well as transforming WordPress to it.
docker run -e "MODE=poly" --name wp-cont --link mysql-cont:mysql -p 80:80 -d polyverse/ps-wp-image
