In the admin area after selecting the news area you will be presented with a list of your news items:
Adding (or indeed amending) news is as simple as filling in a form:
You can choose the image, the title, a brief description as a teaser and of course the main text.
You can elect to have news items shown on the from page, and the number shown:
and if you choose to have your news as a parallax on the front page (as it is on this site) you have the extra options.
If you choose 0 for the number shown on the front page nothing will be shown - obviously!
News is shown in descending date order - latest first!
