 You can use the UI to install extensions, or, you can put your extensions in `data/config/auto/extensions`, there is also the option to create a script `data/config/auto/startup.sh` which will be called on container startup, in case you want to install any additional dependencies for your extensions or anything else.
 
+
 An example of your `startup.sh` might looks like this:
 ```sh
 # install all packages for the extensions
-for s in extensions/*/install.py; do
-  python "$s"
+shopt -s nullglob
+list=(./extensions/*/requirements.txt)
+for req in "${list[@]}"; do
+  pip install -q -r "$req"
 done
+pip install -q --force-reinstall opencv-python-headless 'transformers>=4.24'
 ```
 
+NOTE: dependencies of extensions might get lost when you create a new container, hence the installing them in the startup script is important.

 ### **DONT OPEN AN ISSUE IF A SCRIPT OR AN EXTENSION IS NOT WORKING**
 
 I maintain neither the UI nor the extension, I can't help you.
