Erc20 token upgreadble contract question.

[olvin]

I have a erc20 token upgreadble contract which is deployed at blockchain through remix solidity. Implementation contract is deployed. Now i need to deploy proxy contract. I got the proxy contrsct source code which gets compiled at remix. But when I hit deploy button, it ask me for " _data " input. Can someone help me find what is that _ data? Can someone help me deploy it?
