Etherscan verification: File import callback not supported

Hello,

I'm trying to verify a smart contract at etherscan but when I try it this error appears:

The contract address is at 0xd9b22d452408291210a9bf7749b6ccf91b4d38e4
And the input abi-encoded is 000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000036161610000000000000000000000000000000000000000000000000000000000

I assume that etherscan is not ready to download files from github.

What should I do to verify the smart contract?

Regards!
