 =========
 
-The charts below show how Ceph's requirements map onto various Linux
-platforms.  Generally speaking, there is very little dependence on
-specific distributions outside of the kernel and system initialization
-package (i.e., sysvinit, systemd).

+The chart below shows which Linux platforms Ceph provides packages for, and
+which platforms Ceph has been tested on. 
+
+Ceph does not require a specific Linux distribution. Ceph can run on any
+distribution that includes a supported kernel and supported system startup
+framework, for example ``sysvinit`` or ``systemd``. Ceph is sometimes ported to
+non-Linux systems but these are not supported by the core Ceph effort.
