 ## Overview
 
-The `gofeed` library is comprised of a universal feed parser and several feed specific parsers.   Which one you choose depends entirely on your usecase.  If you will be handling both rss and atom feeds then it makes sense to use the `gofeed.Parser`.  If you know ahead of time that you will only be parsing one feed type then it would make sense to use `rss.Parser` or `atom.Parser`.
-
 #### Universal Feed Parser
 
 The universal `gofeed.Parser` works in 3 stages: detection, parsing and translation.  It first detects the feed type that it is currently parsing.  Then it uses a feed specific parser to parse the feed into its true representation which will be either a `rss.Feed` or `atom.Feed`.  These models cover every field possible for their respective feed types.  Finally, they are *translated* into a `gofeed.Feed` model that is a hybrid of both feed types.  Performing the universal feed parsing in these 3 stages allows for more flexibility and keeps the code base more maintainable by separating RSS and Atom parsing into seperate packages.
@@ -62,6 +44,8 @@ The translation step is done by anything which adheres to the `gofeed.Translator
 
 The `gofeed` library provides two feed specific parsers: `atom.Parser` and `rss.Parser`.  If the hybrid `gofeed.Feed` model that the universal `gofeed.Parser` produces does not contain a field from the `atom.Feed` or `rss.Feed` model that you require, it might be beneficial to use the feed specific parsers.  When using the `atom.Parser` or `rss.Parser` directly, you can access all of fields found in the `atom.Feed` and `rss.Feed` models.  It is also marginally faster because you are able to skip the translation step.
 
+However, for the *vast* majority of users, the universal `gofeed.Parser` is the best way to parse feeds.  This allows the user of `gofeed` library to not care about the differences between RSS or Atom feeds.

It currently supports the [Dublin Core](http://dublincore.org/documents/dces/) and [Apple iTunes](https://help.apple.com/itc/podcasts_connect/#/itcb54353390) extensions which you can access at `Feed.ItunesExt`, `feed.DublinCoreExt` and `Item.ITunesExt` and `Item.DublinCoreExt`
