+**Q**: What’s the difference between ``newt upgrade``, ``newt install``, and ``newt sync``?
 
-**A**: 
-
-- ``newt install``: downloads repos that aren't installed yet.  The downloaded version matches what ``project.yml`` specifies.
-- ``newt upgrade``: performs an install, but also applies to repos that are already installed.
-- ``newt sync``: fetches and pulls the latest for each repo, but does not change the branch (version).
+**A**: Only use ``newt upgrade``.  The other two commands (``install`` and ``sync``) are deprecated and will be removed soon.
