How to Add Mail Account to iPhone

I need assistance adding my homestead email to my iPhone mailboxes. I'm not tech savvy and hope someone can help me. On my iPhone I tried going through Settings>Mail>Accounts>Add Account>Other>Add Mail Account then from there I don't know what needs to be input. Under Incoming Mail Server it asks for Host Name mail.example.com and under Outgoing Mail Server Host name smtp.example.com What goes in those two fields?
