How to play Minecraft Xbox with mods?

I'm sorry to say that 'minecraft' is not available for mods at the moment but will be soon in the future according to rumours.

The only other way you can get mods is to do it a non legal way and get them off some modding sites.
I would not recommend this as they may come with viruses and mess up your computer or Xbox.

I suggest you follow 4J studios twitter and watch out for daily updates there.

Here is a link to there twitter:

Keep on checking daily and soon they may add mods.

I'm sorry I could not help you but just keep waiting and they will be on your xbox in the foreseeable future
