+# RSS feed widget for KDE Plasma 6
+
+A barebones widget for displaying an RSS feed. Shows the title, timestamp, and
+description (without images) of each feed item. Clicking on a feed item opens
+its link in the default browser.
+
+Rescued and adapted for Plasma 6. This was originally written by Andreas Loos,
+2015, and includes selected contributions from Mircea Kitsune, 2017-2018.
