RSSMerge is a simple API that takes the of a list of feeds in plain text and returns an combined feed.
Run make to build a single rssmerge binary that contains the entire application. The application
will run on port 3000.
Run make docker to build a Docker image for your current platform.
Run make publish to build Docker images for multiple platforms and publish them to Docker Hub.
Visit http://localhost:3000 once launched for more instructions.
Essentially you need save a list of the feed URLs in a text file (one per line), publish that file e.g. as a gist on Github and pass on the URL of the file to this application. This application will then fetch the items from all of those feeds listed in the file and return a combined feed.
