This is the detailed theme description page link http://theme.wordpress.com/themes/bueno/
To create a static Page which will not automatically update see here >
Know that Categories will not display until there is a single published post in the Category.
Many bloggers fail to understand that
(1) there is only one page we can post to in any blog and
(2) the static pages http://en.support.wordpress.com/pages/ they create do not automatically update.
Only the dynamic pages like Archives, Categories and Tags created by the software when we publish a post will update automatically update with new posts.
By default the front page of the blog is the post that displays all posts in your blog. Though there is only one dynamic page in a blog for posts (not pages) http://en.support.wordpress.com/post-vs-page/ and we cannot post to more than that one page, we can create the appearance that we have posted to more than one page.
We organize posts by assigning categories to them. You can create a custom menu and add the dynamic categories pages into the custom menu.
Note that there are many common errors, misunderstandings and misconceptions when creating custom menus and you can read about them here. > http://wpbtips.wordpress.com/2011/12/19/custom-menus/
