Installing is pretty easy takes only a minute or two.
Upload 'category-recent-posts-widget.zip' directory to your '/wp-content/plugins/' directory.
Activate the plugin through the 'Plugins' screen in WordPress.
On the 'Widgets' sub-menu of 'Appearance' you will find a new widget type called 'Category Recent Posts'.
Add one or more of these to your themes widget display areas.
For each widget you add, select a title.
For each widget you add, specify the number of posts to display in the widget, show/ hide excerpt or specify the number of words to display in excerpt
Specify the Read More text that will be displayed after the excerpt in the sidebar. This defaults to ellipses [...] if the field is left blank
Save your settings.
That's it. Enjoy!
