+The library does its best to follow the appropriate specifications and not to set the Refresh time
+too soon. It currently follows all update time management methods in the RSS 1.0, 2.0, and Atom 1.0
+specifications. If one is not provided, it defaults to 10 minute intervals. If you are having issues
+with feed providors dropping connections, please let me know and I can increase this default, or you
+can increase the Refresh time manually. The Feed.Update method uses this Refresh time, so if Update
+seems to be returning very quickly with no new items, it's likely not making a request due to the
+provider's Refresh interval.
+
+This is seeing thorough use in [RS3][1], but development is still active.
