+This repo builds and Docker image of [iptv-org/epg](https://github.com/iptv-org/epg).
+The purpose is to make the deployment easier and more suitable for different environments.

+## Docker image
+
+### Paths
+
+An example `channels.xml` is included by default in the image.
+However if you want to configure your own channels you need to provide your own configuration file.
+You can do this by creating a mapping in the `/config` folder.
+
+### Environment Variables
+
+| Variable | Description | Default |
+|-------------------------------|----------------------------------------------------------------------------|------------------|
+| CRON_SCHEDULE | CRON expression describing the recurrence for epg retrieval. | 0 0,12 * * * |
+| DAYS | Describes the desired amount of days in the future for for epg retrieval. | 14 |
+| MAX_CONNECTIONS | The maximum amount of parallel connections that can be established | 10 |
