 - `channel.url` (and related channel defaults)
 - `selectors.items`
 - `selectors.title`
-- `selectors.link` (derived href selector)
+- `selectors.url` (derived href selector)
 - `selectors.description` when a distinct description root exists
 
-Rename `selectors.link` to `selectors.url` before shipping. Item URLs must use the canonical `url` selector key for RSS `<link>` output.

 It does not invent author, `published_at`, categories, or enclosure selectors. Add those manually when the page exposes them reliably.

 ## Recommended Follow-Up
 
-1. Rename `selectors.link` → `selectors.url` if present
-2. Validate: `html2rss validate my-feed.yml`
-3. Render: `html2rss feed my-feed.yml`
-4. Tighten selectors, strategy, or `request.botasaurus` options if needed
-5. For Feed Directory contributions, add `directory.topics` (see [Creating Custom Feeds](/creating-custom-feeds/#sharing-your-config))
