+
+My minibuffer completion system uses =selectrum=, =prescient=, =company=,
+and =marginalia=.  At some point, I'd like to take a deep dive in =embark=
+(possibly switching out =selectrum=), =ido=, =orderless=, or others,
+for now .... I just want to see my completions.

+Prescient can persist itself too.
+
+#+begin_src emacs-lisp :noweb-ref modes
+  (prescient-persist-mode +1)
+#+end_src
+
+Let's have =prescient= and =selectrum= work together.

+*** Consult
+
+#+begin_src emacs-lisp :noweb-ref modes
+  (straight-use-package 'consult)
+  (require 'consult)
+#+end_src
+
+Consult has a lot of great bindings that work well with Emacs's
+default completion system.  These all come from the [[https://github.com/minad/consult#configuration][example configuration]].
+
+#+begin_src emacs-lisp :noweb-ref bindings

+#+end_src
+
+*** Marginalia
+
+Finally, =marginalia= provides extra information about completion
+candidates.
+
+#+begin_src emacs-lisp :noweb-ref packages
+  (straight-use-package 'marginalia)
+  (require 'marginalia)
+#+end_src
+
+#+begin_src emacs-lisp :noweb-ref modes
+  (marginalia-mode +1)
+#+end_src
+
+I like the rich annotations provided by =marginalia=.
+
+#+begin_src emacs-lisp :noweb-ref settings
+  (setq-default marginalia-annotators
+                '(marginalia-annotators-heavy
+                  marginalia-annotators-light
+                  nil))
+#+end_src
+
+**** Integration with Selectrum
+
+#+begin_src emacs-lisp :noweb-ref functions
+  (advice-add #'marginalia-cycle :after
+              (lambda ()
+                (when (bound-and-true-p selectrum-mode)
+                  (selectrum-exhibit))))
