+## Updating dependencies/PRs
+Even though we prefer `mage` to our automation, we still have some
+rules implemented on our `Makefile` as well as CI will use the
+`Makefile`. CI will run `make check-ci`, so make sure to run it
+locally before submitting any PRs to have a quicker feedback instead
+of waiting for a CI failure.
+
+### Generating the `NOTICE.txt` when updating/adding dependencies
+To do so, just run `make notice`, this is also part of the `make
+check-ci` and is the same check our CI will do.
+
+At some point we will migrate it to mage (see discussion on
+https://github.com/elastic/elastic-agent/pull/1108 and on
+https://github.com/elastic/elastic-agent/issues/1107). However until
+we have the mage automation sorted out, it has been removed to avoid
+confusion.
