It’s a free and open source feed reader for macOS.
It’s barely usable at this point. Barely. Probably not even. A whole bunch of things haven’t been done yet. (See the bug tracker).

On accepting pull requests
It’s pretty early still, and we have strong opinions about how we want to do things, so we’re not seeking help just yet.
That said, we will seriously consider any pull requests we do get. Just note that we may not accept them, or we may accept them and do a bunch of revision.
In the future — some time after 5.0 ships — we expect to want contributions. The plan is not to make this a one-person show forever.
