Here's a more detailed approach using information from the reference video, "How to brew a perfect cup of tea with teabags, by Tea Taster Dominic":

Prepare Your Kettle: First, ensure your kettle is filled with fresh water and begin to heat it to a rolling boil. This is important for proper tea brewing.
Turn off Kettle: Once the water is boiling, turn off the kettle, according to the reference, so that it does not overboil and lose oxygen.
Place the Tea Bag: Gently put your chosen tea bag into your cup or teapot.
Pour Hot Water: Immediately pour the hot, just-boiled water directly over the tea bag. As seen in the video, pouring directly onto the tea bag helps with the brewing process.

Water Temperature: Using freshly boiled water is essential to properly extract the flavor from the tea bag.
Avoid Over-Boiling: As indicated in the video, do not let the water boil for too long, so that it doesn't overboil and lose oxygen, affecting the tea’s taste.
Steeping Time: After pouring the water, allow the tea bag to steep for the recommended time, usually a few minutes. This is not mentioned in the video and is not needed to answer how to put the bag in, but is a crucial step in making tea.
