+## Troubleshooting
+
+### If it doesn't work with other components that use react-dnd
+
+react-dnd only allows for one DragDropContext at a time (see: https://github.com/gaearon/react-dnd/issues/186). To get around this, you can import the context-less tree component via `SortableTreeWithoutDndContext`.
+```js
+// before
+import SortableTree from 'react-sortable-tree';
+
+// after
+import { SortableTreeWithoutDndContext as SortableTree } from 'react-sortable-tree';
+```
