not finding instructions to set up my zoho mail to fetch from yahoo

Hi there,  I have been searching this site for a long time but have not yet found clear instructions to set up my zoho mail to fetch mail from my yahoo account. Obviously it's somewhere in the site. I have the info on settings from yahoo, ports etc.,
where in my account do I go to enter the information? Thanks, Jay
