Code Generator

You should get some code to add to your page to have news listed on them.
Actually you would need to have 2 pages.

First page contains news list. You should select appropriate template for news row. If it would contain more link to news description then you have select template that has correct URL or you should modify existing template with correct URL to news description page.
One of good place to put news list is Home Page.
You can select news filtering by Category or User that posted that news.
You can specify Maximum number of news to be shown.
The last drop down menu is Type of the page where you wish insert your news. You can specify PHP, SSI and JS. If your webserver where you would add news does not support PHP or SSI then you can use JS (JavaScript).

Second page is used for news description. When your website visitor clicks "more" link in news list he goes to news description page.
Here you should select Template and Type. It is same fields as for First page.

As result you may have 2 pages setup.

news.php - the list of news with links to description (e.g. more)
desc.php - the news description the common link would contain news ID so that page would have desc.php?id=(SOME ID) look.
