I have just installed the IndieNews plugin but … I don’t understand how to use it.

Syndicating Your Posts
The IndieNews plugin allows you to automatically syndicate your posts to the IndieNews and IndieWeb.xyz sites using webmention. You’ll notice on your posts that in your tags, in addition to the indieweb tag you’ve added, the plugin has automatically added additional tags which include #indienews and /en/indieweb which–instead of being wrapped with links to those tags on your website–are wrapped with links pointing to those websites along with the appropriate syndication markup. As a result, when you publish your posts and send webmentions, both of those services are posting to those services on your behalf.
I’d recommend care in syndicating to them using this plugin as this morning it might appear to some that you’re spamming those channels. I tag lots of things on my site as “IndieWeb” mostly for my own use, so I specifically don’t use the plugin for concern of overwhelming those other sites. Instead I typically cross-post to both services manually using their respective instructions: IndieWeb News and IndieWeb.xyz.
IndieNews Dashboard Widget
The other feature that the plugin does is add a small widget to your main /wp-admin/ dashboard page that also displays a feed of what appears on the IndieNews website for your convenience.
Example of what IndieNews widget looks like in your WordPress dashboard.I’ll admit that the GitHub repo for the plugin doesn’t do as good a job of describing how to use it as it might. Perhaps we ought to file an issue to improve that?
