 # Configuration
 
+## User Interface
+
+Historically Prelude had adopted a very minimalistic approach to UI and
+had hidden by default Emacs's menu bar and tool bar. This was changed a bit
+in Prelude 1.1 for the sake of being more approachable to newcomers to Emacs
+and now the menu bar is displayed by default. The tool bar is still hidden, as
+it's quite big and not that useful.
+
+!!! Tip
+
+    You can toggle the menu bar by pressing `F12`.
+
+Furthermore, Prelude 1.1 displays line numbers (via `global-nlinum-mode`), just
+like most "modern" editors and IDEs do these days. You can go back to the way
+things were by setting `prelude-minimalistic-ui` to `t` in `personal/preload` or
+by adding the following snippets to your personal config:
+
+``` emacs-lisp
+(global-nlinum-mode -1)
+(menu-bar-mode -1)
+```
+
+!!! Note
+
+    The first approach is better as it would prevent those UI elements from
+    appearing temporarily.
