1. Find the package keyName from `slcli order package-list`
2. Find the location from `slcli order package-locations PUBLIC_CLOUD_SERVER`
  If the package does not require a location, use 'NONE' instead.
3. Find the needed items `slcli order item-list PUBLIC_CLOUD_SERVER`
  Some packages, like PUBLIC_CLOUD_SERVER need presets, `slcli order preset-list PUBLIC_CLOUD_SERVER`
4. Find the complex type from https://sldn.softlayer.com/reference
5. Use that complex type to fill out any --extras

    Example::

        slcli order place --verify --preset B1_2X8X100 --billing hourly
        --complex-type SoftLayer_Container_Product_Order_Virtual_Guest
        --extras '{"virtualGuests": [{"hostname": "test", "domain": "ibm.com"}]}'
