+Alfred Clean URLs
+=================
+
+This worklow for [Alfred](https://www.alfredapp.com/) checks your current clipboard for an URL, if it finds one it will try to make the URL as short as possible, but without using third party URL shortening services. It will remove all unnecessary URL information that are not needed to get to the same page, or use an short URL provided by the same service.
+
+[Download](https://github.com/stroebjo/alfred-cleanurls/releases)
+
+Currently supported are:
+
+- Amazon product detail pages
+- Heise news articles
+- reddit threads
+- YoutTube videos
+
+Add new URL
+-----------
+
+If you have a URL that is not currently supported, please create a pull request or open a new issue.
