Dreamplex + Zgemma box - How do I add plugins?

Hi guys,

As the title states, I have a zgemma box with an enigma2 image. I've also installed dreamplex plugin. But the problem is that I don't know how to install any extensions or channels. On the pc it's normally straight forward as I can just download the plugin.bundle and drop it in the Plugins folder, but I don't know how to do this on the zgemma. Any advice would be much appreciated.

Thanks
