-- **On Windows & MAC:** run `docker-machine start default`
+This step is only for **Windows & MAC** users, run the default Host:
 
->If the host "default" does not exist, create it using:

->`docker-machine create -d virtualbox default`
+```bash
+docker-machine start default
+```

+
+If the host "default" does not exist, create one using the command below, else skip it:
+
+```bash
+docker-machine create -d virtualbox default
+```
 
-- **On Linux:** you don't need a virtual host, since Docker runs locally on your machine.
