Does anyone know how to make Gyeran Tang (계란탕)?

I found this website, I hope it's useful.

Ingredients:
3 eggs, ½ cup water, 3 ts of salted shrimp sauce (“sae woo jeot” in Korean) , 2 green onions

In a microwavable bowl, put 3 cracked eggs, ½ cup water, 3 ts salted shrimp sauce, 2 chopped green onions and stir it with a fork
*Tip: If you don’t have sae woo jeot (salted shrimp sauce), you can use 3 ts of fish sauce.
Put it into the microwave oven and cook it for 5 minutes. Serve it with rice.
If no microwave oven is available, you can steam it. In a large pot, pour about 3-4 cups of water and place the bowl that contains the egg mixture in the center of the pot. Close the lid of the pot and cook it over low-medium heat for about 15 minutes.
