Dear Evgeny Eishinsky

First you must have a Google account.

Second your paper must be achieved somewhere on the internet, so there is a link to the paper.

It is wise to upload your paper to a scientific repository (e.g. zenodo.org).

You have to create a personal account on scholar.google.com too.

At this personal page you can adjust papers manually (see the plus sign on the horizontal bar).

With kind regards, Sydney
