  SwiftUI view with formatted markdown. The formatted markdown is wrapped in a `VStack` with no extra view modifiers.
 
  - Parameter markdown: The text needed to be formatted, as a `String`
+ - Parameter alignment: The horizontal alignment of the `VStack` in the view. Default is `.center`, like in default `VStack`.
+ - Parameter spacing: The distance between adjacent subviews, or `nil` if you want the stack to choose a default distance for each pair of subviews.
