Wil you elaborate it please? Actually how can i do that? I have visite byteball.org but what i have to do there?
Go again to byteball.org and download (and install and start) the wallet.
Right under the wallet download link there's a link (on byeball.org) a link to chat with the Transition Bot. Click that special link and the wallet should show the view where you'll discuss with the bot.
There you'll link your Bitcoin wallet to your Byteball wallet - one good method is by signing the message the bot provides.
