 Each line of this file is a url to a rss feed. Pretty simple.
 
+Display the name of the feed in the toots
+-----------------------------------------
+
+If you want to display the name of the feed in the resulting toot, you can do so by giving it a name with the following syntax::
+
+    Le journal du hacker <https://www.journalduhacker.net/rss/>
+
+Then in the `tweet` configuration, you can use the `{feedname}` syntax, which will be replaced by the actual name of the feed.

 Match specific patterns of rss feeds in the uri_list files
 ----------------------------------------------------------
 You can use specific pattern matching for uri in the uri_list file to filter some of the rss entries of a rss feed. Lets modify the previous file::
