# Update System

SquadDNS is delivered as Docker image.

If there is a new version (visible in the administration), you just need to pull the latest image and restart your Docker containers.

## Backup configuration

First make sure to **backup** your current **configuration** folder and files.

## Download latest image

If you use the **latest** tag, just pull the latest version one more time.

```
docker pull boxblinkracer/squad-dns:latest
```

If you use a specific tag, just make sure to set the new version that you want to use in your docker-compose.yml or docker run command.

```
image: boxblinkracer/squad-dns:1.2.0
```

## Restart Containers

After downloading the latest versions, just restart your Docker containers

```
docker-compose down
docker-compose up -d
```
