Markdown Information

Markdown, created by John Gruber of Daring Fireball, is the technology we chose to use to allow rich text within Day One journal entries. Markdown allows italic and bold, along with several other simple formatting options that can be written using plain text and display properly in Read views. Markdown syntax is available in Day One and is toggled On by default.

Day One takes a similar approach to Markdown as GitHub. See GitHub Flavored Markdown.

The best way to see how Markdown formatting works in Day One is to refer to these sample entries:
