 ### cmake-init Template Check
 
+This module allows to check the actuality of the used cmake-init template for own projects.
+This module is usable when the following is integrated into the `CMakeLists.txt`.
+
+```cmake
+# Add cmake-init template check cmake targets
+add_check_template_target(<CMAKE_INIT_SHA>)
+```
+
+Here, the `<CMAKE_INIT_SHA>` contains the git hash of the used cmake-init template.
+Further, the files `cmake/HealthCheck.cmake` and `cmake/CheckTemplate.cmake` are required.
+
+The hash is usually configured using
+
+```cmake
+# Meta information about the project
+set(META_CMAKE_INIT_SHA      "<CMAKE_INIT_SHA>")
+
+# Add cmake-init template check cmake targets
+add_check_template_target(<CMAKE_INIT_SHA>)
+```
+
+Correctly configures, this module adds a cmake build target named `check-template` that compares the passed `<CMAKE_INIT_SHA>` with the current master commit hash of this repository and provides a link for a diff view.
