# Update node

## Node update guide

Update requires updating to the latest node binary.

For a detailed guide, please choose the proper instruction according to the method used to install the node:

* [Automated script](#automated-script-installs) (a.k.a. nodes installed with [this guide](/blockchain/for-validators-nominators-and-stakers/run-a-validator.md#option-1-automatic-script))
* [Docker](#docker-installs)
* [Manual](#manual-installs)

## Automated script installs

Run the following command on your server:

```
curl -sSLO https://raw.githubusercontent.com/liberland/liberland_substrate/main/substrate/scripts/install/install.sh
bash install.sh
```

The installer will detect existing install and perform the required updates without wiping any data or keys. If asked about which network to use - make sure you choose the correct one.

## Docker installs

You need to pull the latest image and recreate your container.

If you followed the [Complete example of running a validator on mainnet](/blockchain/for-developers-and-testers/docker.md) guide, follow these steps:

1. Pull the latest image:

   ```
   docker pull liberland/blockchain-node:latest
   ```
2. Stop and remove the old container. If you followed the guide, it won't remove any data or keys:

   ```
   docker stop liberland && docker rm liberland
   ```
3. Recreate the container:

   ```
   docker run --name liberland -d --network=host --restart always -v $HOME/liberland_data:/data liberland/blockchain-node:latest -d /data --chain mainnet --validator
   ```

## Manual installs

If you've installed manually, you need to:

1. Download latest node binary (`linux_x86_build`) from the [releases page](https://github.com/liberland/liberland_substrate/releases)
2. Stop your node
3. Replace the binary you're using with the downloaded one
4. Restart your node
