**Which one to choose depends on the specific focus of your website.** If your website mainly covers basic information, Option 1 or 2 would be sufficient. If you offer more in-depth guides, Option 3 or 4 would be better. And if you have a wide range of customs-related content, Option 5 is the most comprehensive. Consider what kind of content you *plan* to write and choose the description that best reflects that goal.
