+</note>
+
+<p><app>Evolution</app> offers no graphical interface to customize its tool bars or items in menus.</p>
+
+<p>Advanced users can experiment by exploring and editing the corresponding system-wide file(s) under 
<file>$PREFIX/share/evolution/ui/</file>.</p>
+
+<p>Copy those files with the file ending <file>.ui</file> which you would like to modify to your personal 
configuration folder <file>$HOME/.config/evolution/ui/</file>.
+Modify the files in your personal configuration folder so the next <app>Evolution</app> software update will 
not overwrite your changes.</p>
+
+<p>The modified files will be used if the <code>evolution-ui-version</code> attribute of the root 
<code>ui</code> element matches the version of the default files provided by <app>Evolution</app>.</p>
