 ** Completing in the minibuffer
 
 Corfu can be used for completion in the minibuffer, since it relies on child
-frames to display the candidates. By default, ~global-corfu-mode~ does not
-activate ~corfu-mode~ in the minibuffer, to avoid interference with specialised
-minibuffer completion UIs like Vertico or Mct. However you may still want to
-enable Corfu completion for commands like ~M-:~ (~eval-expression~) or ~M-!~
-(~shell-command~), which read from the minibuffer. Activate ~corfu-mode~ only if
-~completion-at-point~ is bound in the minibuffer-local keymap to achieve this
-effect.
+frames to display the candidates. The Corfu popup can be displayed even if it
+doesn't fully fit inside the minibuffer. There is a caveat however if you use
+EXWM, since then an EXWM buffer will overlap the child frame.
