+    Note that directory listings are cached by default, because fetching those listings can be expensive. This is
+    contrary to local filesystem behaviour. The cache will be cleared if writing from this instance, but it can
+    become stale and return incorrect results if the storage is written to from another process/machine.

+    to configure the caching, call `.invalidate_cache()` when required, or pass `refresh=True` to the
+    various listing methods.
 
     In the default case the cache is never expired. This may be controlled via the ``cache_timeout``
     GCSFileSystem parameter or via explicit calls to ``GCSFileSystem.invalidate_cache``.
