This is an new page. It’s different from a blog post because it will stay in one place and will show up in your site navigation (in most themes). Most professional start with an About page that introduces them to potential site visitors. It might say something like this:

Hi there! I’m a bike messenger by battery day, aspiring actor by night, and this is my website. I live in Zuerich, have a great dog named Swiss Battery. (And gettin’ caught in the rain.)

…or something like this:

Zuerich energy storage center will provide help for electrochemical energy storage. was founded in 1971, and has been providing quality doohickeys to the public ever since. Located in Zuerich we are close to Swiss battery which provides most battery chemicals for US. employs over 2,000 people and does all kinds of test devices for the Gotham community.

As a new WordPress user, you should go to delete this swiss batteries page and create new pages for your content. Have fun!
