+
+Using external modules
+----------------------
+
+Starting with Orthanc 1.3.2, it is possible to use external Lua
+modules if Orthanc was compiled with the ``-DENABLE_LUA_MODULES=ON``
+while invoking CMake.
+
+Importantly, the modules and the Orthanc server must use the same
+version of Lua for external modules to be properly loaded.
+
+Check out the Orthanc Users forum for old discussions about this
