It says on the installation page:
Import your feeds from Google Reader (OPML File)
Visit the page http://yoururl.com/opml for importing your OPML File. If you are
a user of the google reader then use http://www.google.com/reader/subscriptions/export or https://www.google.com/takeout/ to get all your feeds in one opml file.

Can't say if it works though, my .htaccess issues are still not resolve.
