# Quickstart
> Get started with NexaSDK Docker on Linux ARM64 in minutes.
## **Tutorial Video**
## **Installation**
### **Pull Docker Image**
Pull the latest NexaSDK Docker image from Docker Hub:
```bash bash theme={"dark"}
docker pull nexa4ai/nexasdk:latest
```
## **Usage Modes**
NexaSDK Docker supports two usage modes: server mode for REST API access and interactive CLI mode for direct model inference.
### **CLI Mode (Interactive)**
Run NexaSDK in interactive CLI mode for direct model inference:
```bash bash theme={"dark"}
export NEXA_TOKEN="YOUR_LONG_TOKEN_HERE"
docker run --rm -it --privileged \
-v /path/to/data:/data \
-v /etc/machine-id:/etc/machine-id:ro \
-e NEXA_TOKEN \
nexa4ai/nexasdk:latest infer NexaAI/Granite-4.0-h-350M-NPU
```
The `-it` flags enable interactive mode. Replace `NexaAI/Granite-4.0-h-350M-NPU` with any supported model name. For a complete list of supported models, see the [Overview](/en/nexa-sdk-docker/overview#supported-models) page.
### **Server Mode (Detached)**
Run NexaSDK in server mode to expose a REST API endpoint. This mode runs in the background:
```bash bash theme={"dark"}
export NEXA_TOKEN="YOUR_LONG_TOKEN_HERE"
docker run --rm -it --privileged \
-v /path/to/data:/data \
-v /etc/machine-id:/etc/machine-id:ro \
-e NEXA_TOKEN \
nexa4ai/nexasdk:latest pull [MODEL_NAME]
docker run --rm -d -p 18181:18181 --privileged \
-v /path/to/data:/data \
-v /etc/machine-id:/etc/machine-id:ro \
-e NEXA_TOKEN \
nexa4ai/nexasdk:latest serve
```
The `--privileged` flag is required for NPU access. Replace `YOUR_LONG_TOKEN_HERE` with your actual Nexa token. You can obtain a token by creating an account at [sdk.nexa.ai](https://sdk.nexa.ai) and generating one in **Deployment → Create Token**.
`nexa serve` won't auto download models. Make sure to pre-download the models you intend to use.
The server will be accessible at `http://localhost:18181`. For detailed API documentation, see the [REST API](/en/nexa-sdk-docker/RestAPI) page.
