You can just start writing if you've opened up a new document in MacDown, Markdown Edit, or whatever text or Markdown editor you happen to be using.
However, there’s a couple of things you'll note right away:
- Whether you use one space, " ", or many spaces in between your words, it will only render (display with formatting) as if there was one space.
- Just hitting 'Enter' once doesn’t put you on a new line. You need to hit 'Enter' twice.
