+Introduction
+============
+
+Extra CMake Modules (ECM) provides several modules that provide default settings
+(like installation directories, compiler flags and other CMake options) aimed at
+software produced by the KDE modules; these are documented here. ECM also
+provides modules with more general functionality, documented in
+:manual:`ecm-modules(7)`, and ones that extend the functionality of the
+``find_package`` command, documented in :manual:`ecm-find-modules(7)`.
+
+To use these modules, you need to tell CMake to find the ECM package, and
+then add either ``${ECM_MODULE_PATH}`` or ``${ECM_KDE_MODULE_DIR}`` to the
+``CMAKE_MODULE_PATH`` variable:
+
+.. code-block:: cmake
+
+  find_package(ECM REQUIRED NO_MODULE)
+  set(CMAKE_MODULE_PATH ${ECM_MODULE_DIR})
+
+Using ``${ECM_MODULE_PATH}`` will also make the other types of modules
+available.
