+### Emphasis Style
+
+Alias: `emphasis-style`
+
+Makes sure the emphasis style is consistent.
+
+Options:
+- Style: The style used to denote emphasized content
+	- Default: `consistent`
+	- `consistent`: Makes sure the first instance of emphasis is the style that will be used throughout the document
+	- `asterisk`: Makes sure * is the emphasis indicator
+	- `underscore`: Makes sure _ is the emphasis indicator
+
+Example: Emphasis indicators should use underscores when style is set to 'underscore'

+This is ***bold and emphasized***
+This is ***nested bold** and ending emphasized*
+This is ***nested emphasis* and ending bold**
