+### `DASHDOT_FS_VIRTUAL_MOUNTS`
+
+If you want to show a virtual mount in the storage split view, that is ignored in the filter above.
+Can be used for example to show `fuse.mergerfs` mounts, which is basically a grouping of other mounts.
+
+You need to pass the names of the filesystems you want to use. To find out what the name is, execute `df`
+and look at the first column.
+
+Note that this will only be shown in the storage split view (enabled with the
+[`DASHDOT_ENABLE_STORAGE_SPLIT_VIEW`](./config#dashdot_enable_storage_split_view) flag).
+The normal pie chart will not be affected and there will also be no disk shown in the list of the storage
+widget.
