Convert RSS feed OPML File to Friendica ready CSV
You can export an OPML file from your news feed reader and upload it here to convert it to a CSV file ready to import into Friendica en masse.
For Feedly, the OPML export link is here
https://feedly.com/i/opml
After export is done, you can import into Friendica in Settings>Import contacts>Choose File>Save settings
OR go to https://YOURINSTANCEADDRESSHERE/settings/importcontacts
It's not instananeous. I think the server checks for a response before it adds a feed.
***IF YOU HAVE A LOT IT MAY TAKE 20-30 MINUTES,
then 20-30 minutes for the feed content to start showing up.
