-  <description xml:lang="en">OSTree is a tool for developing,
-  building, and deploying Linux-based operating systems.  It is most
-  similar to tools like dpkg and rpm in "Linux
-  distributions". However, it is not a package system (though one
-  could be built on top).</description>
+  <description xml:lang="en">
+    OSTree is best summarized in a single sentence as "git for
+    operating system binaries".  At its core architecture is a
+    userspace content-addressed filesystem, and layered on top of
+    that is an administrative layer that is designed to atomically
+    parallel install multiple bootable Unix-like operating systems.
