+Feed creator example
+--------------------
+
+In the sub-directory *Feed/docs/examples* there is a **feed_creator**
+application which can be used to create simple XML feeds from minimal text
+files.
+
+The structure of the text files accepted by this application is::
+
+ Feed title
+ Feed link
+ Feed author name
+ Feed author email
+ Feed description
+
+ Item 1 title
+ Item 1 link
+ Item 1 author name
+ Item 1 author email
+ Item 1 author description
+
+ Item 2 title
+ Item 2 link
+ Item 2 author name
+ Item 2 author email
+ Item 2 author description
+
+ .. etc
+
+An example of an input text file:
+
+.. include:: examples/feed_creator/data/news.txt
+ :literal:
+
+The **feed_creator** application will read an input file with the above
+structure and output an XML feed of the chosen type (rss1, rss2 or atom). An
+XML file will also be written in the same directory as the input file, with
+the name of the input file plus the *.xml* extension.
+
+Example of usage (current directory is the `feed_creator` directory)::
+
+ php feed_creator.php rss2 data/news.txt
+
+After running this command, the file *data/news.xml* will be created,
+containing an RSS2 feed with the values read from *data/news.txt*:
+
+.. include:: examples/feed_creator/data/news.xml
+ :literal:
