+### 🐳 Ollama Inside Docker
+
+If **Ollama is deployed inside Docker** (e.g., using Docker Compose or Kubernetes), the service will be available:
+
+- **Inside the container**: `http://127.0.0.1:11434`
+- **From the host**: `http://localhost:11435` (if exposed via host network)
+
+#### Step 1: Check Available Models
+
+- Inside the container:
+
+  ```bash
+  docker exec -it openwebui curl http://ollama:11434/v1/models
+  ```
+
+- From the host (if exposed):
+
+  ```bash
+  curl http://localhost:11435/v1/models
+  ```
+
+This command lists all available models and confirms that Ollama is running.
+
+#### Step 2: Download Llama 3.2
+
+Run the following command:
+
+```bash
+docker exec -it ollama ollama pull llama3.2
+```
+
+**Tip:** You can download other models from Hugging Face by specifying the appropriate URL. For example, to download a higher-quality **8-bit version of Llama 3.2**:
+
+```bash
+ollama pull hf.co/bartowski/Llama-3.2-3B-Instruct-GGUF:Q8_0
+```
+
+#### Step 3: Access the WebUI
+
+Once everything is set up, access the WebUI at:
+
+[http://localhost:3000](http://localhost:3000)
