You have signed up for the Calander service. That is step One. Step two would be to copy and paste the code where you want to have the calander--or get the address and make a link to your calender.
You may also manager the look and feel and all that jazz before or after you decide where and how you want to have people access your calender.
I personally like have links I can make to my services rather then copy/paste the code because I can Make my things look the way I want them too.
Either way just saying you want the services does not put them on your site--you still need to take the step of putting it on your site where you want it.
