-**Warning:** the provider uses tagging functionality to be able to invalidate cache on eg. resource upload, edit or delete. In order to support cache tagging, a corresponding tag-aware pool has to be used. If you use a non-tag-aware pool, tagging will be disabled which means that you will experience some issues while using the bundle. Eg. newly uploaded resource might not be visible immediatelly (until the cache doesn't expire) in the browser or search.

+### Cloudinary configuration
+
+#### Folder mode
+
+On June 4th, 2024, Cloudinary has introduced a setting called `folder_mode` which changes the connection between folders and resource public ID. This required some changes in how this bundle works. You can read more [here](https://cloudinary.com/documentation/folder_modes).
+
+All new accounts are automatically set to `dynamic` mode and this can't be changed, while old accounts are still in `fixed` mode. This can be changed but once changed to `dynamic`, it can't be switched back.
+
+So in order to support both modes, there's a parameter with the same name here, and it has to be properly configured. You can check your mode in your Cloudinary dashboard.
+
+```yaml
+netgen_remote_media:
+    cloudinary:
+        folder_mode: dynamic
+```
+
+Default value is `dynamic` and another available mode is `fixed` (for old accounts).
