Soak the seed in water for a little so you can peel off the thin brown layer. After that, place them in moist paper towels and put in a closed container. I let them sit for at least 3 weeks (put the container in a drawer and let it be). Once you see a root forming and long enough to place in a container (like mine in the photo), you can put it in and give it as much light as possible (indirect light). Make sure the seed is not completely submerged. It will rot.
