Use Icy Cold Beer Dispenser with home made beer

[Quihubo]

Hi Everybody,
I Have an Icy Cold beer dispenser that I used to use with Heineken mini kegs, now that I'm starting to do some home brewing beer I would like to use it for my own beer, therefore I would like to know if some one may know how to start using it with my own beer, all the suggestions and proposals are welcomed.

I'm adding pictures of the dispenser.

Thanks in advance for your help.

Regard
