-### npm Linkcheck
-
-If you installed the Antora dependencies via `npm install`, then a broken link checker is available. To run it, you must have one terminal open and run `npm serve` to start a http server and in another terminal using the following command:
-
-```console
-npm linkcheck http://localhost:8080/server/next | grep "BROKEN"
-```

-#### Example Output

-Note: in the example output above, only the first entry is a genuine broken link.
-All the others in the list are example links, and therefore not broken.
