Error in Remix Compiler

[Benedicity948]

I just started lesson 2, and on compiling the first line of code, I noticed it has been giving me this similar warning.
"Warning: SPDX license identifier not provided in source file. Before publishing, consider adding a comment containing "SPDX-License-Identifier: " to each source file. Use "SPDX-License-Identifier: UNLICENSED" for non-open-source code. Please see https://spdx.org for more information.
--> contracts/Simplestorage.sol
"

Please does anyone have a solution to this?

Hey @Benedicity948 ,
The warning is thrown because you have not mentioned the "SPDX-License-identifier" , this warning does not stop your solidity code from compiling , but its always best to have it mentioned , You can add the License Identifier by adding a comment on the very first line of the code , that is for example :

// SPDX-License-Identifier: MIT  

pragma solidity ^0.8;

contract SimpleStorage{
      ............
      }
