+STATEMENT: >>>
+StrictDoc uses caching when reading and writing artifacts. By default, all caches are written to the system's temporary directory (``$TMPDIR``).
+
+The ``cache_dir`` option in the configuration file allows specifying a custom directory, such as ``./output/build``. This setting can help make caching artifacts visible alongside documentation artifacts.
