Yep, that's a new plone site @newbazz.
At this point, you should be able to log in to the site using the admin username and password that you set up when you installed Plone. Once you've logged in, you'll see a black bar to the side of the site that offers controls for adding, editing, and managing "content". Plone is a "CMS" or content management system. It's purpose is to allow you to create, through the web, a website filled with pages and images and news items and lots of other types of content. You will be able to "publish" the content you create, which controls whether a user who is not logged in can see it. You'll be able to add other users, or allow people to register themselves. You'll also be able to control things like what types of content are available, how that content is displayed, and even what the theme will look like that controls how your entire site looks.
Now that you have a Plone site, you should read our documentation on how to work with content. It will help you answer many of the questions that arise as you begin playing with your new Plone site. You'll probably also have questions that are not covered in the documentation. Those questions should be brought here for the community to help you with. If you like, you might even help to edit the documentation and add the answers to the questions you come up with.
Keep up the good work. You're doing great!
