+### Bold Style
+
+Next to color highlighting Nord Vim makes use of <strong>bold</strong> font styles for various syntax elements to make them stand out more as well as better representing their syntactic meaning.

+The theme includes **bold** font styles for specific syntax elements. To **disable bold font styles**, set the `nord_bold` theme configuration variable:
+
+```viml

 ### Italic Style
 
 In terminal mode Nord Vim doesn't make use of <em>italic</em> font styles in order to prevent unexpected styles and color highlighting. This design decision is based on the known problems of most terminals related to special font styles like <em>italic</em>.
