# Quick Start: Importing Your First Hymn

Choralis reads **.zip** hymn packages. Each hymn should be packaged as one ZIP archive containing its audio tracks and optional files such as sheet music and metadata.

### Audio Tracks

Include one audio file for each voice part.

**Supported formats:** MP3, WAV, M4A, OGG, AAC, FLAC

**Important:** All audio tracks must be pre-synchronized. They must have the same duration and begin at exactly the same point so they remain aligned during playback.

### Preparing Your ZIP File

**1. Align your audio tracks.**
Make sure all tracks have the same duration and starting point.

**2. Name each track according to its voice part:**

* `soprano.mp3`
* `alto.mp3`
* `tenor.mp3`
* `bass.mp3`

**3. Add an optional `info.txt` file** containing hymn information:

```text
Lyrics: John Doe
Music: John Doe
Arrangement: John Doe
Info: Information about the hymn
Tags: Recessional, Ordinary
Tempo: 80
```

**4. Add your sheet music PDF**, if available.

**5. ZIP everything together.**
The ZIP filename becomes the hymn title in Choralis.

For example:

`Amazing_Grace.zip`

will appear as:

**Amazing Grace**

**6. Transfer the ZIP file to your phone.**

**7. Open Choralis, select Import, and choose the ZIP file.**

That's it! Choralis will extract and organize the hymn in your library.

### 🔐 Password-Protected ZIP Files

Choralis also supports encrypted, password-protected ZIP archives.
