Feature Article?

For English I have to write a feature article on the informative text 'Hiroshima'. I really don't have a clue in the world what to write or where to start; can anybody help me?

Isn't a feature article like a newspaper article, magazine article, etc? Correct me if I'm wrong. And like chronos said just try to find out as much info on the subject as you can from books, websites, and things like that. Also remember to site your sources and give credit to any info you have gotten from these sites, as teachers are sometimes picky about this.
