sudo ln -sf /usr/lib/polkadot/polkadot /usr/local/bin/polkadot
```

***Create working directory***

```bash
mkdir -p $HOME/.kusama
chown -R $(id -u):$(id -g) $HOME/.kusama
```

***Configure and Create a Systemd Service***

```bash
current_user=$(whoami)
STARTNAME="Your_Node_Name"
```

<pre class="language-bash"><code class="lang-bash">sudo tee /etc/systemd/system/kusama.service > /dev/null &#x3C;&#x3C;EOF

***Start and Enable the Service***

```bash
sudo systemctl daemon-reload
sudo systemctl enable kusama.service
sudo systemctl restart kusama.service
sudo journalctl -u kusama.service -f
```

{% hint style="info" %}
After launch, we wait for our node to synchronize. You can track our condition using [TELEMETRY](https://telemetry.polkadot.io/#list/0xb0a8d493285c2df73290dfb7e61f870f17b41801197a149ca93654499ea3dafe)
{% endhint %}

After the node has synchronized, we pull out the key from our node by entering the command

```bash
curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "author_rotateKeys", "params":[]}' http://localhost:9933
```

#### *Creating a validator* <a href="#creating-a-validator" id="creating-a-validator"></a>

* Go to the [chain](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fkusama-rpc.dwellir.com#/accounts) and first create a wallet
* We create a validator. To do this, select `Network - Staking - Accounts - Validator`
