 This container bundles Local AI and auto-configures it for you.
 
 ### Notes
-- After the container was started the first time, you should see a new `nextcloud-aio-local-ai` folder when you open the files app with the default `admin` user. In there you should see a `models` folder. Now you can download models from e.g. https://download.nextcloud.com/server/apps/stt_whisper/ or https://download.nextcloud.com/server/apps/llm/ or others that are mentioned in https://localai.io/model-compatibility/index.html#model-compatibility-table and put them into the `models` folder. ⚠️⚠️ Please refer to https://localai.io/features/ how each model needs to be named. Afterwards restart all containers from the AIO interface and the models should automatically get active. Additionally after doing so, you might want to enable or disable specific features for your models in the integration_openai settings: `https://your-nc-domain.com/settings/admin/connected-accounts`
+- After the container was started the first time, you should see a new `nextcloud-aio-local-ai` folder when you open the files app with the default `admin` user. In there you should see a `models.yaml` config file. You can now add models in there. Please refer [here](https://github.com/go-skynet/model-gallery/blob/main/index.yaml) where you can get further urls that you can put in there. Afterwards restart all containers from the AIO interface and the models should automatically get downloaded by the local-ai container and activated.
+- Example for content of `models.yaml`:
+```yaml
+# Stable Diffusion in NCNN with c++, supported txt2img and img2img 
+- url: github:go-skynet/model-gallery/stablediffusion.yaml
+
+# Port of OpenAI's Whisper model in C/C++ 
+- url: github:go-skynet/model-gallery/whisper-base.yaml
+  name: whisper-1
+
+# A commercially licensable model based on GPT-J and trained by Nomic AI on the v0 GPT4All dataset.
+- url: github:go-skynet/model-gallery/gpt4all-j.yaml
+  name: gpt4all-j
+```
+-  Additionally after doing so, you might want to enable or disable specific features for your models in the integration_openai settings: `https://your-nc-domain.com/settings/admin/connected-accounts`
+- The models folder where models get downloaded to is covered by AIOs backup solution
 - See https://github.com/nextcloud/all-in-one/tree/main/community-containers how to add it to the AIO stack
