-*** Software Heritage is
-    - a /reference archive/ of /all/ FOSS ever written
-    - a unique /complement/ for /development platforms/
-    - an international, open, nonprofit, /mutualized infrastructure/
-    - at the service of our community, at the service of society
+*** 
+    - It is urgent to preserve software _source code_; Software Heritage has
+      took a _systematic approach_ at it and has already assembled the _largest
+      archive_ to date.
+    - Software Heritage responds to _cultural, research, and industry needs_;
+      it is a _shared infrastructure_ that can benefit us all.
+    - We should collaborate and pool _resources_ to make it so.
