The document provides guidelines for user interface design conventions in a clinical software system, including: - Buttons should be primary or secondary, with primary buttons emphasizing the most common actions. Secondary buttons are for less frequent actions. - Dates should generally be displayed in a relative format like "May 15, 2017" unless it is a birthdate. Exact dates include both date and time. - Required fields are indicated with an asterisk. The system checks for and alerts the user about incomplete required fields. - Other conventions cover colors, fields, messages, popovers, tabs, text formatting, and more. The guidelines aim to provide consistency across applications.
