This page is known as the home or index page and is the first thing that any visitors to your site will see.
This is where you will include brief text about you, your business, what you sell or provide etc.
Do keep it brief here - as people may lose interest if the page is too long.
You can also replace the image at the side to one which is more appropriate to your business and add new images to the page.
If you have experience of html you will easily be able to make the changes to the code yourself.
If not you may want to consider using our competitively priced Changes Services.
