Titles and sections

For a while I hadn't been able to figure out how to change title sections from the original theme ones. I have figured out how to change this by going into the  settings. In the Image below you can see that i have changed 'Gallery' to 'Line Up'.

I have added an 'About' section as the brief says the website requires one, I have put this right at the top of the website under the header, this way if a user comes to the website and isn't sure what it's for, then it would take a couple of seconds to find the about page by either scrolling down once or clicking the about tab.
