 title: Shaman Storage System

 Flamenco comes with a storage system named *Shaman*. It makes it possible to
 have independence of render jobs, as well as as-fast-as-possible uploads to the
 farm. Shaman is built into Flamenco Manager.

-## Enabling Shaman
+## Enabling or Disabling Shaman
 
-In `flamenco-manager.yaml`, set `shaman.enabled: true` like this:
+Shaman is enabled by default on Linux and macOS. Since on Windows symbolic links
+are not that commonly used, and require some additional system permission (see
+[Windows](#windows)), Shaman is disabled by default there.
+
+To enable Shaman, edit `flamenco-manager.yaml` and set `shaman.enabled: true`
+like this:
 
 ```yaml
 shaman:
   enabled: true
 ```
 
+Similarly, it can be disabled by setting it to `false`.

+{{< hint type=warning >}}
+
+After changing this setting, be sure to **restart** Flamenco Manager, and
+**refresh** the connection in the Blender add-on preferences. The last step is
+necessary to make Blender fetch the updated configuration.
