What exactly do you do after installing WPMUDEV Dashboard Plugins?

Wordpress Noob's here! Look I know wordpress is easy so I installed it and I'm only good as installing theme and then install plugin without configuring. Anything past that, I'm so lost. But I do have experience with post and page to complete the site.

Anyhow I installed WPMUDEV dashboard and used one of the theme, and created few pages.

But after creating the pages, I can't seem to put contents like Google Maps or calendar or even forms.

Can anyone help me how to input or anything. I just joined this membership and it seems, if you don't know Wordpress at all then this isn't for me.
