Techniques on this tutorial will work for Joomla! all Joomla! Versions ( From 1.5.x to 3.x )
RSS feeds for joomla! content are only available for the following:

- Joomla! Featured Articles
In the Joomla Admin you can get any category ID in the Category Manager, you can construct the feed url yourself even if it has no menu item on your website:
FEATURED ARTICLE FEED
MAKING A FEED FROM A CATEGORY BLOG MENU ITEM USING SEF LINKS
You can also simply navigate to a category blog or featured blog menu item that is already created and has friendly URL's which show just the SEF alias' copy it and add ?format=feed&type=rss or ?format=feed&type=atom. Here is an example:
FULL TEXT OR INTRO TEXT?
In each menu item configuration you have "Integration Options" in the right panel that allow you to decide if you want that item to show the full text or just the intro text as well as show/hide the "read More.." link.
Also, you can set a global setting for Full/Intor text from the Article Manager. In the admin, simply navigate to the Article Manager and click on the "Options" icon in the upper right of the screen and go to the "Integration" tab.
