+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.
+
+
+## Dependencies
+[Node](https://nodejs.org/en)<br>
+[pm2](https://www.npmjs.com/package/pm2)<br>
+[serve](https://www.npmjs.com/package/serve)<br>

+## 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.
