## Getting Started
> ⚠️ **IMPORTANT:** You must complete the following steps before running LiveCaptions Translator for the first time.
>
> For detailed information, see Microsoft's guide on [Using live captions](https://support.microsoft.com/en-us/windows/use-live-captions-to-better-understand-audio-b52da59c-14b8-4031-aeeb-f6a47e6055df).
### Step 1: Verify Windows LiveCaptions Availability
Confirm LiveCaptions is available on your system using any of these methods:
- Toggle **Live captions** in the quick settings

- Access via **Quick settings** > **Accessibility** > **Live captions**
- Open **Start** > **All apps** > **Accessibility** > **Live captions**

### Step 2: Configure LiveCaptions
When you first start, Windows LiveCaptions will ask for your consent to process voice data on your device and prompt you to download language files to be used by on-device speech recognition.
After launching Windows LiveCaptions, click the **⚙️ gear** icon to open the setting menu, then select **Position** > **Overlaid on screen**.
