In aPeel it's very easy to include content from other sites by using RSS.  New feeds can be added to your site on the 'RSS Feeds' tab. 

Insert a single feed as a text list

To insert a feed into a layout, template or page you can use this code:

{{ rss_feeds.handle | feed_item_list: }}

You should replace 'handle' with the handle of the feed you want to grab.

Insert a single feed as an image list

To insert an image based version of a feed you can use this:

{{ rss_feeds.flickr | feed_image_list: }}

Insert a merged list of all feed items as a text list

{{ rss_feeds.all_merged | feed_item_list: }}

Insert a merged list of all feed items as an image list

{{ rss_feeds.all_merged | feed_image_list: }}
