Main Message on Homepage

On the home page of this theme, it has a section that says: “Start Your Own Blogging Network and CommunityLorem ipsum dolor sit amet, consectetuer adipiscing elit. Quisque sed felis. Aliquam sit amet felis. Mauris semper, velit semper laoreet dictum, quam diam dictum urna, nec placerat elit nisl in quam. Etiam augue pede, molestie eget, rhoncus at, convallis ut, eros”

Where do go I change that wording? Also, how to change the image to the right of it?
