-
-> 1. Action buttons must be explicitly shown by setting text to them. The buttons will be hidden in any dialog type if no text is passed for them. This also allows you to display neutral or negative action buttons individually without relying on positive text. 
-> 2. List dialogs now use CharSequence arrays rather than String arrays.
-> 3. Other bug fixes are included.

 ### Global Theming
 
-If you don't want to manually make calls to `theme()` everytime you construct a dialog, you can put a single attribute in
-your Activity themes that makes all dialogs dark.
+By default, the dialog inherits and extracts theme colors from other attributes and theme colors of the app
+or operating system. This behavior can be overridden in your Activity themes:
 
 ```xml
 <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
 
+    <!--
+        All dialogs will default to Theme.DARK
+    -->
     <item name="md_dark_theme">true</item>
 
+    <!--
+        By default, the title text is pure black or pure white based on the theme
+    -->
+    <item name="md_title_color">#E91E63</item>
+
+    <!--
+        By default, the content text is derived from the ?android:textColorSecondary OS attribute
+    -->
+    <item name="md_content_color">#9C27B0</item>
+
+    <!--
+        By default, the accent color is derived from the colorAccent attribute of AppCompat or
+        android:colorAccent attribute of the Material theme
+    -->
+    <item name="md_accent_color">#673AB7</item>

 </style>
