Hi there.
Usually you'll have to add oil to the surface with a kitchen towel. (Not one that loses fiber). Or a clean cloth would be preferred.
Then heat the pan up until it smokes slightly. This embeds the oil inside the coating or adds a coating but it doesn't last forever. Once done your not allowed to scrub the surface and never use washing liquid on the pan it will rust it through.
Keep it oiled and you should be fine.
Hope this helps?
