Syncing contacts from phone to Gmail

[android who knew]

Brand new Android user! Bought the Note 7 three hours before the recall. Winning.
I'm wondering how I can sync the contacts that are on my device with my Gmail? I have the Gmail Ap and the Samsung Email ap's on the Note 7, but I also use Gmail on my pc.
I'd like to be able to enter a contact into the phone's contacts, and be able to use it when writing an email on my pc (or in the Gmail phone Ap for that matter).
Much appreciated.
