+Introduction
+============
+
+Extra CMake Modules (ECM) provides various modules that provide useful functions
+for CMake scripts. ECM actually provides three types of modules that can be
+used from CMake scripts: those that extend the functionality of the
+``find_package`` command are documented in :manual:`ecm-find-modules(7)`; those
+that provide standard settings for software produced by the KDE community are
+documented in :manual:`ecm-kde-modules(7)`.  The rest provide macros and
+functions for general use by CMake scripts and are documented here.
+
+To use these modules, you need to tell CMake to find the ECM package, and
+then add either ``${ECM_MODULE_PATH}`` or ``${ECM_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 find modules and KDE modules
+available.
+
+Note that there are also toolchain modules, documented in
+:manual:`ecm-toolchains(7)`, but these are used by users building the software
+rather than developers writing CMake scripts.
