+ ### Album Level Ranges
+
+ It is possible to specify not just a nunmber for `album-levels`, but a range from level x to level y in the folder structure that should make up an album's name:  
+ `--album-levels="2,3"`  
+ The range is applied to the folder structure beneath `root_path` from the top for positive levels and from the bottom for negative levels.
+ Suppose the following folder structure for an external library with the script's `root_path` set to `/external_libs/photos`:
+ ```
+/external_libs/photos/2020/2020 02 Feb/Vacation
+/external_libs/photos/2020/2020 08 Aug/Vacation
+```
+ - `--album-levels="2,3"` will create albums (for this folder structure, this is equal to `--album-levels="-2"`)
+    - `2020 02 Feb Facation`
+    - `2020 08 Aug Vacation`
+  - `--album-levels="2,2"` will create albums (for this folder structure, this is equal to `--album-levels="-2,-2"`)
+    - `2020 02 Feb`

+⚠️ Note that with negative `album-levels` or album level ranges, images from different parent folders will be mixed in the same album if they reside in sub-folders with the same name (see `Vacation` in example above).
 
 Since Immich does not support real nested albums ([yet?](https://github.com/immich-app/immich/discussions/2073)), neither does this script.
