# Introduction & installation

To control your rig with Smart Logger you have to download a companion app on your PC.

{% hint style="info" %}
Smart Logger Companion is based on the hamlib library, with hundreds of radio models compatible.
{% endhint %}

\
\
You can download it on your PC from the settings menu "RIG COMPANION"

{% hint style="warning" %}
Since the companion app hasn't been downloaded many times yet, you may need to **confirm the download in the browser** and, when opening the installer, you may need to **click "More info" and "RUN" if smart screen opens** on windows.\
\
As more users download the application, Microsoft and Chrome will stop requesting confirmation.
{% endhint %}

{% hint style="success" %}
You can also download the companion app from here:

<a href="https://smartlogger.app/app/companion/Smart%20Logger%20Companion%20Setup.exe" class="button primary">DOWNLOAD - WINDOWS</a>
{% endhint %}

{% hint style="info" %}
The companion is currently only available for windows, but more OSs are on the way!
{% endhint %}
