 #### Version detection
 
-CMake determines the Icinga 2 version number using `git describe` if the
-source directory is contained in a Git repository. Otherwise the version number
-is extracted from the `ICINGA2_VERSION` file. This behavior can be
-overridden by creating a file called `icinga-version.h.force` in the source
-directory. Alternatively the `-DICINGA2_GIT_VERSION_INFO=OFF` option for CMake
-can be used to disable the usage of `git describe`.
+CMake determines the Icinga 2 version number using `git describe` if the source directory is contained
+in a Git repository or if the source directory has been extracted from an archive built with `git-archive`.
+Otherwise the version number is specified in the `ICINGA2_VERSION` variable in the main `CMakeLists.txt`
+file. The `-DICINGA2_GIT_VERSION_INFO=OFF` option for CMake can be used to disable the usage of
+`git describe`.
