The header image is made of various eco icons so to say, the stretch of green will feature your blog title and a brief description.
Below it on the right is the internal search box, followed by the horizontal menu bar. The main column has the headline and date stamp on top and other post details like author, time, comments and labels at the bottom of the post.
On uploading the template you might get the undefined error message for the date stamp, to fix that go to Layout--Settings--Formating--Timestamp Format and select the right format. You can also watch this video guide to get further help.
