\[ See tutorials for how to open terminal on [Mac](https://www.howtogeek.com/682770/how-to-open-the-terminal-on-a-mac/) & [Windows](https://www.wikihow.com/Open-Terminal-in-Windows) ]

Copy/Paste the operating-system-specific command below into your terminal:

{% tabs %}
{% tab title="Linux/Mac/PREberry/Windows-Powershell" %}
`docker stop presearch-node ; docker rm presearch-node ; docker stop presearch-auto-updater ; docker rm presearch-auto-updater ; docker run -d --name presearch-auto-updater --restart=unless-stopped -v /var/run/docker.sock:/var/run/docker.sock presearch/auto-updater --cleanup --interval 900 presearch-auto-updater presearch-node ; docker pull presearch/node ; docker run -dt --name presearch-node --restart=unless-stopped -v presearch-node-storage:/app/node -e REGISTRATION_CODE=YOUR_REGISTRATION_CODE_HERE presearch/node ; docker logs -f presearch-node`
{% endtab %}

{% tab title="Windows-Command Line" %}
`docker stop presearch-node & docker rm presearch-node & docker stop presearch-auto-updater & docker rm presearch-auto-updater & docker run -d --name presearch-auto-updater --restart=unless-stopped -v /var/run/docker.sock:/var/run/docker.sock presearch/auto-updater --cleanup --interval 900 presearch-auto-updater presearch-node & docker pull presearch/node & docker run -dt --name presearch-node --restart=unless-stopped -v presearch-node-storage:/app/node -e REGISTRATION_CODE=$YOUR_REGISTRATION_CODE_HERE presearch/node & docker logs -f presearch-node`
{% endtab %}
{% endtabs %}

{% hint style="warning" %}
**IMPORTANT:** You need to insert your registration code from step #2 above into the script by replacing the text`YOUR_REGISTRATION_CODE_HERE`with your actual registration code. So, for example, if your registration code is `XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX` then the final command would contain the text `REGISTRATION_CODE=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX` .
{% endhint %}

The above command installs two services on your computer, the ***presearch-node*** and the ***presearch-auto-updater*****,** and configure both of them to be always running in the background.&#x20;

The *presearch-node* actually runs the decentralized search software, whereas the *presearch-auto-updater* is responsible for automatically upgrading the *presearch-node* to the newest versions when released to ensure the node stays up to date and can continue to connect to the Presearch network.
