```

## Usage

If converting from a text file:

``` js
import fs from 'fs';
import vtt2srt from 'vtt-to-srt';

fs.createReadStream(__dirname + '/subtitles.vtt')
  .pipe(vtt())
  .pipe(fs.createWriteStream(__dirname + '/subtitles.srt'));

```

``` js
import fs from 'fs';
import vtt2srt from 'vtt-to-srt';

const vttString = 'WEBVTT FILE\r\n1\r\n00:00:01.000 --> 00:00:02.000\r\nthis is WebVTT';

const srtStream = vtt2srt();

srtStream.write(vttString);
srtStream.end();
srtStream.pipe(fs.createWriteStream(__dirname + '/subtitles.srt'));

```
