-Tired of seeing lots of actual stars ~*~ in your headers, and you want a
-fancier remplacement? Or you are still using ~org-bullets~ but just
-found out how out-of-date and abandoned it is? (Last commit was on
-September 18th, 2014… damn…) Search no more, ~org-superstar~ will take
-care of that for you!
+Org-modern modernizes a bit the appearance of org buffers, including
+tables, source blocks, and tags,, and it applies settings similar to
+~org-superstar~ which I used to use.
