Adsense InFeed

Hi,
is it possible to have a guide on how to insert manually the adsense infeed code on the hueman and hueman pro theme?

With various plugin (Advanced Ads and Ad Inserter) the ads unit are not displayed (or displayed incorrectly). I wanted at this point to enter the code manually, but I do not know in which file of hueman theme I should enter it….

A guide on how to do it would be really useful for many publishers.
Thanks.
