Content sources are the feeds that supply your show with raw material. Mato checks them on a schedule, scores what it finds for relevance, and pulls from the best matches when it writes an episode. Without at least one source, Mato has nothing to work from.
Open your sources
From your show, click Sources under Plan in the sidebar.

A new show shows an empty table with a single Add a source button.
Add a feed
Click Add a source in the top right to open the dialog.

- Feed address is the RSS or Atom URL. Most news sites link one from their footer. Paste it and click Check feed (or press Enter).
- A preview card shows what Mato would read from the feed today: its title, item count, and newest item, so you can confirm it's the right one before adding it.
- How often Mato checks it is a choice of every hour, every day, or every week.
- Only keep articles about is an optional set of include keywords. Leave it empty to keep everything the feed publishes.
- Under More options, Skip articles about lets you exclude articles matching any of those words.
Click Add source. Mato starts reading the feed right away, and a success message confirms it.
If the address isn't a feed Mato can parse, the check fails with a message saying so. Double-check the URL and try again.
Manage your sources
Every source you add appears as a row in the table, with its check frequency, when it was last fetched, how many articles it found in the last 30 days, and its status: Active, Paused, or Failing.

Filter chips across the top (All, Active, Paused, Failing) narrow the list, each with a count, a search box filters by name, and a menu on the right sorts the table (for example, Most articles). A failing source shows the reason right in its row, such as no new articles since a given date, along with inline Edit address and Try again buttons, so you don't need a separate page to fix it.
Open a row's ··· menu for Check now (fetch immediately, without waiting for the schedule), Edit, Pause or Resume, and Delete.
See what a source found
Click a source's name to open its articles.

The top of the page counts the source's articles, how many were kept for writing, skipped, not scored yet, and featured. If new articles haven't been scored for your show yet, a banner offers Score them now, and Check now fetches the feed without waiting for the schedule.
Each article shows its published date, a relevance score once Mato has scored it, and a status such as Kept or Not scored. Chips above the table filter to All, Kept, Featured, or Not scored. Click a row to open a side panel with why Mato kept or skipped it, its talking points, a link to the original, and a Featured switch that moves it to the front of the queue for the next episode. A Make an episode from it button jumps straight into the episode wizard with that article pre-loaded.
You can also add a single article by URL from this page's menu, without waiting for the feed to pick it up.
