 ## Modifying assets

 User can choose to add or override those files. 
 Resources will be overridden when in `pluginConfiguration` block there is a resource with the same name.
 
+## Modifying footer
+
+Dokka supports custom messages in the footer via `footerMessage` string property on base plugin configuration. 
+Keep in mind that this value will be pased exactly to the output html, so it has to be valid and escaped correctly.
+
+## Separating inherited members
+
+By setting a boolean property `separateInheritedMembers` dokka will split inherited members (like functions, properties etc.) 
+from ones declared in viewed class. Separated members will have it's own tabs on the page.
+
 ### Examples
 In order to override a logo and style it accordingly a simple css file named `logo-styles.css` is needed:
