+## Configuration
+
+The MCP server container can be configured via environment variables. All configuration options available to the standalone server are supported.
+
+### Environment Variables Reference
+
+| Environment Variable         | Default Value     | Description                                            |
+| ---------------------------- | ----------------- | ------------------------------------------------------ |
+| `MCP_TRANSPORT`              | `streamable-http` | Transport protocol (`stdio`, `sse`, `streamable-http`) |
+| `MCP_HOST`                   | `0.0.0.0`         | Host to bind to (for HTTP transports)                  |
+| `MCP_PORT`                   | `5000`            | Port to bind to (for HTTP transports)                  |
+| `NGUI_COMPONENT_SYSTEM`      | `json`            | Component system (`json`, `rhds`)                      |
+| `NGUI_PROVIDER`              | `langchain`       | Inference provider (`mcp`, `llamastack`, `langchain`)  |
+| `NGUI_MODEL`                 | `gpt-4o`          | Model name (required for non-MCP providers)            |
+| `NGUI_PROVIDER_API_BASE_URL` | -                 | Base URL for OpenAI-compatible API                     |
+| `NGUI_PROVIDER_API_KEY`      | -                 | API key for the LLM provider                           |
+| `NGUI_PROVIDER_LLAMA_URL`    | -                 | LlamaStack server URL (if `llamastac` is used)         |
+
+### Usage Examples
+
+#### Basic Usage with Ollama (Local LLM)
+```bash
+podman run --rm -it -p 5000:5000 \
+    --env MCP_PORT="5000" \
+    --env NGUI_MODEL="llama3.2" \
+    --env NGUI_PROVIDER_API_BASE_URL="http://host.containers.internal:11434/v1" \
+    --env NGUI_PROVIDER_API_KEY="ollama" \
+    quay.io/next-gen-ui/mcp
+```
+
+#### OpenAI Configuration
+```bash
+podman run --rm -it -p 5000:5000 \
+    --env NGUI_MODEL="gpt-4o" \
+    --env NGUI_PROVIDER_API_KEY="your-openai-api-key" \
+    quay.io/next-gen-ui/mcp
+```
+
+#### Using with Environment File
+Create a `.env` file:
+```bash
+# .env file
+MCP_PORT=5000
+MCP_HOST=0.0.0.0
+MCP_TRANSPORT=streamable-http
+NGUI_COMPONENT_SYSTEM=json
+NGUI_PROVIDER=langchain
+NGUI_MODEL=gpt-4o
+NGUI_PROVIDER_API_KEY=your-api-key-here
+```
+
+Run with environment file:
+```bash
+podman run --rm -it -p 5000:5000 --env-file .env quay.io/next-gen-ui/mcp
+```
+
+#### LlamaStack Provider
+```bash
+podman run --rm -it -p 5000:5000 \
+    --env NGUI_PROVIDER="llamastack" \
+    --env NGUI_MODEL="llama3.2-3b" \
+    --env NGUI_PROVIDER_LLAMA_URL="http://host.containers.internal:5001" \
+    quay.io/next-gen-ui/mcp
+```
+
+### Network Configuration
+
+For local development connecting to services running on the host machine:
+- Use `host.containers.internal` to access host services (works with Podman and Docker Desktop)
+- For Linux with Podman, you may need to use `host.docker.internal` or the host's IP address
+- Ensure the target services (like Ollama) are accessible from containers
