+# SystemTap Puppet Module #
+
+A Puppet module for configuring SystemTap development servers and the runtime
+environment required to run compiled SystemTap probes.
+
+# Usage #
+
+To configure a development environment where SystemTap probes can be compiled,
+include systemtap::devserver. The following sample probe can be executed on the
+development server to check if the basic SystemTap functionalities are working
+fine: `stap -e 'probe oneshot { println("hello world") }'`.
+
+Production machines can be configured to run SystemTap probes by including
+systemtap::runtime.
