I lost my remote for apple tv and would like to use my ipad mini as the remote. Is this possible?

I am not sure if I can program or whatever my ipad mini to use as the renote for our apple tv. We cannot find the remote and I thought I read somewhere tht one can set up their ipad device to act as a remote for apple tv. I could be wrong. Maybe it means sharing some other thisngs between computers but not usinghte ipad as a remote for apple tv. Any information abou this mater would be greatly appreciated!

Thanks,
