About usage of w3c validator

I have tried to check any error with my projects using w3c validator. But the result is kind of long. I have heard that there is a way to generate a link so that it is easier for you guys to debug but I saw no way of doing that.

Therefore, what is the best way/proper way to show the error messages and codes generated by the validator so that you guys can debug.

fix the errors you can, give a link to your project, and explain which errors you are not able to solve on your own
