Markdown Emphasis & Styling
You can add emphasis to your text by making it bold or italic. You can also combine these styles for even greater emphasis.
Italic
To make text italic (corresponding to the HTML em tag), wrap it in one asterisk (*) or one underscore (_).
Bold
To make text bold (corresponding to the HTML strong tag), wrap it in two asterisks (**) or two underscores (__).
Bold and Italic
To make text both bold and italic, wrap it in three asterisks (***) or three underscores (___).
Which Method to Use?
Markdown processors generally don't care whether you use asterisks or underscores, but it's usually recommended to be consistent and stick with one style throughout your document. That said, asterisks tend to be more commonly used for emphasis.
