+== Compiling GF with C run-time system support ==
+
+The C run-time system is separate implementation of the PGF run-time services
+that makes it possible to work with very large, ambiguous grammars, using
+probabilistic models to obtain probable parses.
+
+Support for calling the C run-time library is available in the web API
+provided by ``gf -server``, if C run-time support is enabled.
+
+To enable the C run-time system, first go to the ``src/runtime/c`` directory
+and follow the instructions in the ``INSTALL`` file to install the C run-time
+system. Once this is done, you can install GF with C run-time support by
+doing
+
+```
+cabal install -fserver -fc-runtime
+```
+from the top directory.

 == Creating .deb packages for Ubuntu ==
 
-This has been tested on Ubuntu 12.04, and the resulting ``.deb`` packages
-appears to work on Ubuntu 12.04, 12.10 and 13.04.
+This was tested on Ubuntu 14.04 for the release of GF 3.6, and the
+resulting ``.deb`` packages appears to work on Ubuntu 12.04, 13.10 and 14.04.
 
 Under Ubuntu, Haskell executables are statically linked against other Haskell
 libraries, so the .deb packages are fairly self-contained.
