Shipping Configuration -> Shipping Settings screen, a common change you will want to make is
to change the "Is a Shipping Selection Required?" setting from no to yes.
One of the first things you will probably want to do is define at least one shipping method
Shipping Configuration -> Shipping Methods screen. However,
when you have done this your new shipping method will not show up during checkout to users unless
you have also switched the "Is a Shipping Selection Required?" setting from no to yes.
SoftSlate Commerce is distributed with this setting turned off so you can place test orders immediately after installation, without having to define a shipping method.
